Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-198 advisory.

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

 A flaw was found in the libxml2 library in functions used to manipulate the xmlBuf and the xmlBuffer types. A substantial input causes values to calculate buffer sizes to overflow, resulting in an out-of- bounds write. (CVE-2022-29824)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update libxml2 --releasever=2022.0.20221102' to update your system.
