Fedora 36 : libxml2 / xmlsec1 (2022-aeafd24818)

high Nessus Plugin ID 169199

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 36 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2022-aeafd24818 advisory.

 - An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. (CVE-2022-40303)

 - An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. (CVE-2022-40304)

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

Solution

Update the affected libxml2 and / or xmlsec1 packages.
