Description

The remote host is affected by the vulnerability described in GLSA-202210-03 (libxml2: Multiple Vulnerabilities)

- valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. (CVE-2022-23308)

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

Solution

All libxml2 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=dev-libs/libxml2-2.10.2
