The version of openssl installed on the remote host is prior to 1.0.2k-16.153. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1482 advisory.

  - Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument     in some cases where the input length is close to the maximum permissable length for an integer on the     platform. In such cases the return value from the function call will be 1 (indicating success), but the     output length value will be negative. This could cause applications to behave incorrectly or crash.
    OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to     OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out     of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should     upgrade to 1.0.2y. Other users should upgrade to 1.1.1j.

    Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). (CVE-2021-23840)

  - The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based     on the issuer and serial number data contained within an X509 certificate. However it fails to correctly     handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is     maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a     potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by     OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on     certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are     affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x     and below are affected by this issue.

An     attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate     privileges within the Ghostscript and access files outside of restricted areas or execute commands.
    (CVE-2019-14869)

  - It was found that the superexec operator was available in the internal dictionary in ghostscript before     9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the     file system outside of the constrains imposed by -dSAFER. (CVE-2019-3835)

  - It was found that the forceput operator could be extracted from the DefineResource method in ghostscript     before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access     to the file system outside of the constrains imposed by -dSAFER. (CVE-2019-3838)

The version of kernel installed on the remote host is prior to 4.14.219-161.340. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1600 advisory.

  - A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was     a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a     denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege     to a kernel information leak threat. (CVE-2020-27825)

  - In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking     in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal     in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker     has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are     proxied via an attacker-selected backstore. (CVE-2020-28374)

  - ** DISPUTED ** fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a     subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via     READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this     attack; see also the exports(5) no_subtree_check default behavior. (CVE-2021-3178)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.

The version of openssl installed on the remote host is prior to 1.0.2k-19. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1608 advisory.

  - OpenSSL 1.0.2 supports SSLv2. If a client attempts to negotiate SSLv2 with a server that is configured to     support both SSLv2 and more recent SSL and TLS versions then a check is made for a version rollback attack     when unpadding an RSA signature. Clients that support SSL or TLS versions greater than SSLv2 are supposed     to use a special form of padding. A server that supports greater than SSLv2 is supposed to reject     connection attempts from a client where this special form of padding is present, because this indicates     that a version rollback has occurred (i.e. both client and server support greater than SSLv2, and yet this     is the version that is being requested). The implementation of this padding check inverted the logic so     that the connection attempt is accepted if the padding is present, and rejected if it is absent. This     means that such as server will accept a connection if a version rollback attack has occurred. Further the     server will erroneously reject a connection if a normal SSLv2 connection attempt is made. Only OpenSSL     1.0.2 servers from version 1.0.2s to 1.0.2x are affected by this issue. In order to be vulnerable a 1.0.2     server must: 1) have configured SSLv2 support at compile time (this is off by default), 2) have configured     SSLv2 support at runtime (this is off by default), 3) have configured SSLv2 ciphersuites (these are not in     the default ciphersuite list) OpenSSL 1.1.1 does not have SSLv2 support and therefore is not vulnerable to     this issue. The underlying error is in the implementation of the RSA_padding_check_SSLv23() function. This     also affects the RSA_SSLV23_PADDING padding mode used by various other functions. Although 1.1.1 does not     support SSLv2 the RSA_padding_check_SSLv23() function still exists, as does the RSA_SSLV23_PADDING padding     mode. Applications that directly call that function or use that padding mode will encounter this issue.
    However since there is no support for the SSLv2 protocol in 1.1.1 this is considered a bug and not a     security issue in that version. OpenSSL 1.0.2 is out of support and no longer receiving public updates.
    Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j.

  - Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument     in some cases where the input length is close to the maximum permissable length for an integer on the     platform. In such cases the return value from the function call will be 1 (indicating success), but the     output length value will be negative. This could cause applications to behave incorrectly or crash.

  - The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based     on the issuer and serial number data contained within an X509 certificate. However it fails to correctly     handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is     maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a     potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by     OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on     certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are     affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x     and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving     public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should     upgrade to 1.1.1j.

The version of glibc installed on the remote host is prior to 2.26-41. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1605 advisory.

  - The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple     suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite     loop when processing invalid multi-byte input sequences, leading to a denial of service. (CVE-2016-10228)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text     containing an irreversible character, fails an assertion in the code path and aborts the program,     potentially resulting in a denial of service. (CVE-2020-29562)

  - An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc     2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative     value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the     'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-     of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows     for program execution to continue in scenarios where a segmentation fault or crash should have occurred.
    The dangers occur in that subsequent execution and iterations of this code will be executed with this     corrupted data. (CVE-2020-6096)

The version of flatpak installed on the remote host is prior to 1.0.9-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1597 advisory.

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. A bug     was discovered in the `flatpak-portal` service that can allow sandboxed applications to execute arbitrary     code on the host system (a sandbox escape). This sandbox-escape bug is present in versions from 0.11.4 and     before fixed versions 1.8.5 and 1.10.0. The Flatpak portal D-Bus service (`flatpak-portal`, also known by     its D-Bus service name `org.freedesktop.portal.Flatpak`) allows apps in a Flatpak sandbox to launch their     own subprocesses in a new sandbox instance, either with the same security settings as the caller or with     more restrictive security settings. For example, this is used in Flatpak-packaged web browsers such as     Chromium to launch subprocesses that will process untrusted web content, and give those subprocesses a     more restrictive sandbox than the browser itself. In vulnerable versions, the Flatpak portal service     passes caller-specified environment variables to non-sandboxed processes on the host system, and in     particular to the `flatpak run` command that is used to launch the new sandbox instance. A malicious or     compromised Flatpak app could set environment variables that are trusted by the `flatpak run` command, and     use them to execute arbitrary code that is not in a sandbox. As a workaround, this vulnerability can be     mitigated by preventing the `flatpak-portal` service from starting, but that mitigation will prevent many     Flatpak apps from working correctly. This is fixed in versions 1.8.5 and 1.10.0. (CVE-2021-21261)

The version of dnsmasq installed on the remote host is prior to 2.76-16. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1587 advisory.

  - A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq     checks in the forward.c:reply_query() if the reply destination address/port is used by the pending     forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query,     substantially reducing the number of attempts an attacker on the network would have to perform to forge a     reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's     attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache     Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful     attack is reduced. The highest threat from this vulnerability is to data integrity. (CVE-2020-25684)

  - A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq     checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a     weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1     when it is) this flaw allows an off-path attacker to find several different domains all having the same     hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it     accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the     attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache     Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced.
    The highest threat from this vulnerability is to data integrity. (CVE-2020-25685)

  - A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an     existing pending request for the same name and forwards a new request. By default, a maximum of 150     pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name.
    This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that     it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the     Birthday Attacks section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a     successful attack is reduced. The highest threat from this vulnerability is to data integrity.

  - ** DISPUTED ** In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove     function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously     created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel     developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of     debugfs within blktrace. (CVE-2019-19770)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was     using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of     bounds. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25656)

  - A flaw memory leak in the Linux kernel performance monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this flaw to starve the resources causing denial of     service. (CVE-2020-25704)

  - An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users     can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271.

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

The version of tomcat7 installed on the remote host is prior to 7.0.107-1.39. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1472 advisory.

  - In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used     an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led     to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly     handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered     unlikely. (CVE-2020-1935)
