high Nessus Plugin ID 213665

Synopsis

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

Description

The version of expat installed on the remote host is prior to 2.1.0-15.35. It is, therefore, affected by a vulnerability as referenced in the ALAS-2025-1953 advisory.

An issue was discovered in libexpat before 2.6.3. xmlparse.c does not reject a negative length for XML_ParseBuffer. (CVE-2024-45490)
