Synopsis
The remote Rocky Linux host is missing a security update.Description
The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:5317 advisory.- In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. (CVE-2022-29824)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
