According to the versions of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances     where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection     were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other     places in the script where the file names of certificates being hashed were possibly passed to a command     executed through the shell. This script is distributed by some operating systems in a manner where it is     automatically executed. On such operating systems, an attacker could execute arbitrary commands with the     privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the     OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in     OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze). (CVE-2022-2068)

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt     the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was     preexisting in the memory that wasn't written. In the special case of 'in place' encryption, sixteen bytes     of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and     DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q     (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-147 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to its self-reported version, the Tenable Nessus application running on the remote host is between 8.15.4 and 8.15.8. It is, therefore, affected by multiple vulnerabilities in OpenSSL prior to version 1.1.1t:
    
    - An attacker that had observed a genuine connection between a client and a server could use the flaw to send trial       messages to the server and record the time taken to process them. After a sufficiently large number of messages       the attacker could recover the pre-master secret used for the original connection. (CVE-2022-4304)

    - The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes any header data and the payload       data. Under certain conditions, a double free will occur. This will most likely lead to a crash. (CVE-2022-4450)

    - The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. Under certain conditions,       the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal pointers to the previously       freed filter BIO. This will most likely result in a crash. (CVE-2023-0215)

    - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of       the data under some circumstances. In the special case of in place encryption, sixteen bytes of the plaintext would be       revealed. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p). (CVE-2022-2097)         Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5818 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-6224 advisory.

  - The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This     script is distributed by some operating systems in a manner where it is automatically executed. On such     operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of     the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.
    Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
    Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd). (CVE-2022-1292)

  - In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances     where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection     were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other     places in the script where the file names of certificates being hashed were possibly passed to a command     executed through the shell.

Fixed in OpenSSL 1.1.1q     (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

  - The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where     the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful     verification) even in the case where the response signing certificate fails to verify. It is anticipated     that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the     `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a     certificate verification failure. The normal expected return value in this case would be 0. This issue     also impacts the command line OpenSSL ocsp application. When verifying an ocsp response with the
    -no_cert_checks option the command line application will report that the verification is successful even     though it has in fact failed. In this case the incorrect successful response will also be accompanied by     error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL     3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1343)

  - The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the     memory occuppied by the removed hash table entries. This function is used when decoding certificates or     keys. If a long lived process periodically decodes certificates or keys its memory usage will expand     without bounds and the process might be terminated by the operating system causing a denial of service.
    Also traversing the empty hash table entries will take increasingly more time. Typically such long lived     processes might be TLS clients or TLS servers configured to accept client certificate authentication. The     function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in     OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1473)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202210-02 (OpenSSL: Multiple Vulnerabilities)

  - The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to     compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In     such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent     over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across     multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites.
    This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL     1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v). (CVE-2020-1968)

  - In order to decrypt SM2 encrypted data an application is expected to call the API function     EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the     out parameter can be NULL and, on exit, the outlen parameter is populated with the buffer size     required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer     and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the out parameter. A bug     in the implementation of the SM2 decryption code means that the calculation of the buffer size required to     hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size     required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the     application a second time with a buffer that is too small. A malicious attacker who is able present SM2     content for decryption to an application could cause attacker chosen data to overflow the buffer by up to     a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing     application behaviour or causing the application to crash. The location of the buffer is application     dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).
    (CVE-2021-3711)

  - ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a     buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings     which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not     a strict requirement, ASN.1 strings that are parsed using OpenSSL's own d2i functions (and other similar     parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will     additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for     applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array     by directly setting the data and length fields in the ASN1_STRING array. This can also happen by using     the ASN1_STRING_set0() function. Numerous OpenSSL functions that print ASN.1 data have been found to     assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for     strings that have been directly constructed. Where an application requests an ASN.1 structure to be     printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the     application without NUL terminating the data field, then a read buffer overrun can occur. The same thing     can also occur during name constraints processing of certificates (for example if a certificate has been     directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the     certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the     X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions. If a malicious actor can cause an     application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL     functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack).
    It could also result in the disclosure of private memory contents (such as private keys, or sensitive     plaintext). Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected     1.0.2-1.0.2y). (CVE-2021-3712)

  - There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are     affected, including some of the TLS 1.3 default curves. Impact was not analyzed in detail, because the     pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that     attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not     believed likely. Attacks against DH are considered just feasible (although very difficult) because most of     the work necessary to deduce information about a private key may be performed offline. The amount of     resources required for such an attack would be significant. However, for an attack on TLS to be     meaningful, the server would have to share the DH private key among multiple clients, which is no longer     an option since CVE-2016-0701. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0.0. It was     addressed in the releases of 1.1.1m and 3.0.1 on the 15th of December 2021. For the 1.0.2 release it is     addressed in git commit 6fc1aaaf3 that is available to premium support customers only. It will be made     available in 1.0.2zc when it is released. The issue only affects OpenSSL on MIPS platforms. Fixed in     OpenSSL 3.0.1 (Affected 3.0.0). Fixed in OpenSSL 1.1.1m (Affected 1.1.1-1.1.1l). Fixed in OpenSSL 1.0.2zc-     dev (Affected 1.0.2-1.0.2zb). (CVE-2021-4160)

  - The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop     forever for non-prime moduli. Internally this function is used when parsing certificates that contain     elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point     encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has     invalid explicit curve parameters. Since certificate parsing happens prior to verification of the     certificate signature, any process that parses an externally supplied certificate may thus be subject to a     denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they     can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients     consuming server certificates - TLS servers consuming client certificates - Hosting providers taking     certificates or private keys from customers - Certificate authorities parsing certification requests from     subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that     use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS     issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate     which makes it slightly harder to trigger the infinite loop. However any operation which requires the     public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-     signed certificate to trigger the loop during verification of the certificate signature. This issue     affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the     15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected     1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778)

  - The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This     script is distributed by some operating systems in a manner where it is automatically executed. On such     operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of     the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.
    Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
    Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd). (CVE-2022-1292)

  - The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the     memory occuppied by the removed hash table entries. This function is used when decoding certificates or     keys. If a long lived process periodically decodes certificates or keys its memory usage will expand     without bounds and the process might be terminated by the operating system causing a denial of service.
    Also traversing the empty hash table entries will take increasingly more time. Typically such long lived     processes might be TLS clients or TLS servers configured to accept client certificate authentication. The     function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in     OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1473)

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt     the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was     preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes     of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and     DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q     (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is running a version between 5.21.0 and 5.23.1 and is therefore affected by multiple vulnerabilities in OpenSSL prior to version 1.1.1t:
    
    - A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to       recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an       attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability       affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. (CVE-2022-4304)

    - Vulnerability in the Enterprise Manager Ops Center product of Oracle Enterprise Manager (component:       Networking (OpenSSL)). The supported version that is affected is 12.4.0.0. Easily exploitable       vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Enterprise       Manager Ops Center. Successful attacks of this vulnerability can result in takeover of Enterprise       Manager Ops Center. (CVE-2022-1292)

    - The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the name, any header data and the       payload data. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case       PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that       has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead       to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to       achieve a denial of service attack. The OpenSSL asn1parse command line application is also impacted by this issue.       (CVE-2022-4450)

    - The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used       internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user       applications. The function receives a BIO from the caller, prepends a new BIO_f_asn1 filter BIO onto the front of it to form a       BIO chain, and then returns the new head of the BIO chain to the caller. Under certain conditions, for example if a CMS recipient       public key is invalid, the new filter BIO is freed and the function returns a NULL result indicating a failure. However, in this       case, the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal pointers to the previously       freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO then a use-after-free will occur. This will most likely       result in a crash. (CVE-2023-0215)

The version of Node.js installed on the remote host is prior to 14.20.0, 16.16.0, 18.5.0. It is, therefore, affected by multiple vulnerabilities as referenced in the July 7th 2022 Security Releases advisory.

  - The llhttp parser in the http module does not correctly parse and validate Transfer-Encoding headers. This     can lead to HTTP Request Smuggling (HRS).

    (CVE-2022-32215)

  - The IsAllowedHost check can easily be bypassed because IsIPAddress does not properly check if an IP     address is invalid or not. When an invalid IPv4 address is provided (for instance 10.0.2.555 is provided),     browsers (such as Firefox) will make DNS requests to the DNS server, providing a vector for an attacker-     controlled DNS server or a MITM who can spoof DNS responses to perform a rebinding attack and hence     connect to the WebSocket debugger, allowing for arbitrary code execution. This is a bypass of     CVE-2021-22884. More details will be available at CVE-2022-32212 after publication. Thank you to Axel     Chong for reporting this vulnerability. Impacts: (CVE-2022-32212)

  - This vulnerability can be exploited if the victim has the following dependencies on Windows machine:
    Whenever the above conditions are present, node.exe will search for providers.dll in the current user     directory. After that, node.exe will try to search for providers.dll by the DLL Search Order in Windows.
    It is possible for an attacker to place the malicious file providers.dll under a variety of paths and     exploit this vulnerability. More details will be available at CVE-2022-32223 after publication. Thank you     to Yakir Kadkoda from Aqua Security for reporting this vulnerability. Impacts: Note: Node.js can use an     OpenSSL configuration file by specifying the environment variable OPENSSL_CONF, or using the command line     option --openssl-conf, and if none of those are specified will default to reading the default OpenSSL     configuration file openssl.cnf. Node.js will only read a section that is by default named nodejs_conf. If     your installation was using the default openssl.cnf file and is affected by this breaking change you can     fall back to the previous behavior by: (CVE-2022-32223)

  - When Node.js starts on linux based systems, it attempts to read     /home/iojs/build/ws/out/Release/obj.target/deps/openssl/openssl.cnf, which ordinarily doesn't exist. On     some shared systems an attacker may be able create this file and therefore affect the default OpenSSL     configuration for other users. Thank you to Michael Scovetta from the OpenSSF Alpha-Omega project for     reporting this vulnerability. Impacts: (CVE-2022-32222)

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt     the entirety of the data under some circumstances.  This could reveal sixteen bytes of data that was     preexisting in the memory that wasn't written.  In the special case of in place encryption, sixteen     bytes of the plaintext would be revealed.

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the openssl-3.0.7-18.el9 build changelog.

  - Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied     by a server. That function may return a negative return value to indicate an internal error (for example     out of memory). Such a negative return value is mishandled by OpenSSL and will cause an IO function (such     as SSL_connect() or SSL_do_handshake()) to not indicate success and a subsequent call to SSL_get_error()     to return the value SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be returned by     OpenSSL if the application has previously called SSL_CTX_set_cert_verify_callback(). Since most     applications do not do this the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be     totally unexpected and applications may not behave correctly as a result. The exact behaviour will depend     on the application but it could result in crashes, infinite loops or other similar incorrect responses.
    This issue is made more serious in combination with a separate bug in OpenSSL 3.0 that will cause     X509_verify_cert() to indicate an internal error when processing a certificate chain. This will occur     where a certificate does not include the Subject Alternative Name extension but where a Certificate     Authority has enforced name constraints. This issue can occur even with valid chains. By combining the two     issues an attacker could induce incorrect, application dependent behaviour. Fixed in OpenSSL 3.0.1     (Affected 3.0.0). (CVE-2021-4044)

  - The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop     forever for non-prime moduli. Internally this function is used when parsing certificates that contain     elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point     encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has     invalid explicit curve parameters. Since certificate parsing happens prior to verification of the     certificate signature, any process that parses an externally supplied certificate may thus be subject to a     denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they     can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients     consuming server certificates - TLS servers consuming client certificates - Hosting providers taking     certificates or private keys from customers - Certificate authorities parsing certification requests from     subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that     use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS     issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate     which makes it slightly harder to trigger the infinite loop. However any operation which requires the     public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-     signed certificate to trigger the loop during verification of the certificate signature. This issue     affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the     15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected     1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778)

  - c_rehash script allows command injection (CVE-2022-1292)

  - Signer certificate verification returned inaccurate response when using OCSP_NOCHECKS (CVE-2022-1343)

  - OPENSSL_LH_flush() breaks reuse of memory (CVE-2022-1473)

  - the c_rehash script allows command injection (CVE-2022-2068)

  - AES OCB fails to encrypt some bytes on 32-bit x86 (CVE-2022-2097)

  - X.509 Email Address Buffer Overflow (CVE-2022-3602, CVE-2022-3786)

  - A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint     checking. Note that this occurs after certificate chain signature verification and requires either a CA to     have signed the malicious certificate or for the application to continue certificate verification despite     failure to construct a path to a trusted issuer. The read buffer overrun might result in a crash which     could lead to a denial of service attack. In theory it could also result in the disclosure of private     memory contents (such as private keys, or sensitive plaintext) although we are not aware of any working     exploit leading to memory contents disclosure as of the time of release of this advisory. In a TLS client,     this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the     server requests client authentication and a malicious client connects. (CVE-2022-4203)

  - A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient     to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful     decryption an attacker would have to be able to send a very large number of trial messages for decryption.
    The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS     connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An     attacker that had observed a genuine connection between a client and a server could use this flaw to send     trial messages to the server and record the time taken to process them. After a sufficiently large number     of messages the attacker could recover the pre-master secret used for the original connection and thus be     able to decrypt the application data sent over that connection. (CVE-2022-4304)

  - The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the name (e.g.
    CERTIFICATE), any header data and the payload data. If the function succeeds then the name_out,     header and data arguments are populated with pointers to buffers containing the relevant decoded data.
    The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results     in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate     the header argument with a pointer to a buffer that has already been freed. If the caller also frees this     buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an     attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service     attack. The functions PEM_read_bio() and PEM_read() are simple wrappers around PEM_read_bio_ex() and     therefore these functions are also directly affected. These functions are also called indirectly by a     number of other OpenSSL functions including PEM_X509_INFO_read_bio_ex() and SSL_CTX_use_serverinfo_file()     which are also vulnerable. Some OpenSSL internal uses of these functions are not vulnerable because the     caller does not free the header argument if PEM_read_bio_ex() returns a failure code. These locations     include the PEM_read_bio_TYPE() functions as well as the decoders introduced in OpenSSL 3.0. The OpenSSL     asn1parse command line application is also impacted by this issue. (CVE-2022-4450)

  - The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is     primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may     also be called directly by end user applications. The function receives a BIO from the caller, prepends a     new BIO_f_asn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the     BIO chain to the caller. Under certain conditions, for example if a CMS recipient public key is invalid,     the new filter BIO is freed and the function returns a NULL result indicating a failure. However, in this     case, the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal     pointers to the previously freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO then     a use-after-free will occur. This will most likely result in a crash. This scenario occurs directly in the     internal function B64_write_ASN1() which may cause BIO_new_NDEF() to be called and will subsequently call     BIO_pop() on the BIO. This internal function is in turn called by the public API functions     PEM_write_bio_ASN1_stream, PEM_write_bio_CMS_stream, PEM_write_bio_PKCS7_stream, SMIME_write_ASN1,     SMIME_write_CMS and SMIME_write_PKCS7. Other public API functions that may be impacted by this include     i2d_ASN1_bio_stream, BIO_new_CMS, BIO_new_PKCS7, i2d_CMS_bio_stream and i2d_PKCS7_bio_stream. The OpenSSL     cms and smime command line applications are similarly affected. (CVE-2023-0215)

  - An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7     data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is     an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL     does not call this function however third party applications might call these functions on untrusted data.
    (CVE-2023-0216)

  - An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA     public key by the EVP_PKEY_public_check() function. This will most likely lead to an application crash.
    This function can be called on public keys supplied from untrusted sources which could allow an attacker     to cause a denial of service attack. The TLS implementation in OpenSSL does not call this function but     applications might call the function if there are additional security requirements imposed by standards     such as FIPS 140-3. (CVE-2023-0217)

  - There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
    X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME     incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently     interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL     checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may     allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or     enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate     chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these     inputs, the other input must already contain an X.400 address as a CRL distribution point, which is     uncommon. As such, this vulnerability is most likely to only affect applications which have implemented     their own functionality for retrieving CRLs over a network. (CVE-2023-0286)

  - A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or     signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library     but the implementation of the hash algorithm is not available the digest initialization will fail. There     is a missing check for the return value from the initialization function which later leads to invalid     usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused     by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider.
    PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS     implementation in OpenSSL does not call these functions however third party applications would be affected     if they call these functions to verify signatures on untrusted data. (CVE-2023-0401)
