The version of glibc installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-4806 advisory.

  - A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function May access memory that     has been freed, resulting in an application crash. This issue is only exploitable when a NSS module     implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the
    _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the     call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and     AI_V4MAPPED as flags. (CVE-2023-4806)

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

The remote host is affected by the vulnerability described in GLSA-202310-03 (glibc: Multiple vulnerabilities)

  - An issue was discovered in the GNU C Library (glibc) 2.36. When the syslog function is passed a crafted     input string larger than 1024 bytes, it reads uninitialized memory from the heap and prints it to the     target log file, potentially revealing a portion of the contents of the heap. (CVE-2022-39046)

  - A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and     the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048     bytes can potentially disclose stack contents through the function returned address data, and may cause a     crash. (CVE-2023-4527)

  - A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that     has been freed, resulting in an application crash. This issue is only exploitable when a NSS module     implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the

  - A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the     GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted     GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with     elevated privileges. (CVE-2023-4911)

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.1011 advisory.

  - Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11,     5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server     for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J     through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using     a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to     recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown     vectors. (CVE-2008-5161)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
