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

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with     a nonzero XML_CONTEXT_BYTES. (CVE-2022-23852)

  - Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. (CVE-2022-23990)

  - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks     for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

  - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters     into namespace URIs. (CVE-2022-25236)

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.

The version of AHV installed on the remote host is prior to 20220304.242. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.242 advisory.

  - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many     distant matches. (CVE-2018-25032)

  - A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed     by OpenLDAP's slapd server, to trigger an assertion failure. The highest threat from this vulnerability is     to system availability. (CVE-2020-25709)

  - A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this     vulnerability is to system availability. (CVE-2020-25710)

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116. (CVE-2020-26137)

  - An issue was discovered in SaltStack Salt before 3003.3. A user who has control of the source, and     source_hash URLs can gain full file system access as root on a salt minion. (CVE-2021-21996)

  - Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to     remote code execution in certain Python applications that accept floating-point numbers as untrusted     input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used     unsafely. (CVE-2021-3177)

  - A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is     a setuid tool designed to allow unprivileged users to run commands as privileged users according     predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly     and ends trying to execute environment variables as commands. An attacker can leverage this by crafting     environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully     executed the attack can cause a local privilege escalation given unprivileged users administrative rights     on the target machine. (CVE-2021-4034)

  - ** DISPUTED ** An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through     14.0. It permits the visual reordering of characters via control sequences, which can be used to craft     source code that renders different logic than the logical ordering of tokens ingested by compilers and     interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such     that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium     offers the following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for     m_groupSize. (CVE-2021-46143)

  - 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)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22822)

  - build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22823)

  - Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with     a nonzero XML_CONTEXT_BYTES. (CVE-2022-23852)

  - In Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28, plugins/sql.c does not escape the password for a SQL     INSERT or UPDATE statement. (CVE-2022-24407)

  - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks     for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

  - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters     into namespace URIs. (CVE-2022-25236)

  - A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function     and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for     the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream     object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary     files inside the directories of connecting peers. The server chooses which files/directories are sent to     the client. However, the rsync client performs insufficient validation of file names. A malicious rsync     server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory     and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)

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

  - Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and     expanded. The standard format for interpolation is ${prefix:name}, where prefix is used to locate an     instance of org.apache.commons.text.lookup.StringLookup that performs the interpolation. Starting with     version 1.5 and continuing through 1.9, the set of default Lookup instances included interpolators that     could result in arbitrary code execution or contact with remote servers. These lookups are: - script -     execute expressions using the JVM script execution engine (javax.script) - dns - resolve dns records -     url - load values from urls, including from remote servers Applications using the interpolation defaults     in the affected versions may be vulnerable to remote code execution or unintentional contact with remote     servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons     Text 1.10.0, which disables the problematic interpolators by default. (CVE-2022-42889)

  - A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function     and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for     the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream     object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

  - The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and     8.5.38 to 8.5.78 for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an     untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and     integrity protection, it does not protect against all risks associated with running over any untrusted     network, particularly DoS risks.
