medium Nessus Plugin ID 172822
Synopsis
The remote CBL Mariner host is missing one or more security updates.Description
The version of pkgconf 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-2023-24056 advisory.- In pkgconf through 1.9.3, variable duplication can cause unbounded string expansion due to incorrect checks in libpkgconf/tuple.c:pkgconf_tuple_parse. For example, a .pc file containing a few hundred bytes can expand to one billion bytes. (CVE-2023-24056)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
