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-20230302.2008 advisory.

  - 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)

  - Under some circumstances, this weakness allows a user who has access to run the ps utility on a machine,     the ability to write almost unlimited amounts of unfiltered data into the process heap. (CVE-2023-4016)

  - There's a memory leak in yajl 2.1.0 with use of yajl_tree_parse function. which will cause out-of-memory     in server and cause crash. (CVE-2023-33460)

  - 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
    _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 these issues but has instead relied only on the application's self-reported version number.

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

  - A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been     freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is     called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
    (CVE-2023-4813)

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.

    (CVE-2023-4813)

  - A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a     memory leak, which may result in an application crash. (CVE-2023-5156)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that     has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo     function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or     SUCCESS=merge. (CVE-2023-4813)

Note that Nessus relies on the presence of the package as reported by the vendor.
