The version of AHV installed on the remote host is prior to 20201105.2298. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20201105.2298 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)

  • 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)

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