Amazon Linux 2 : apr (ALAS-2024-2721)

medium Nessus Plugin ID 213340

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of apr installed on the remote host is prior to 1.7.2-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2721 advisory.

Lax permissions set by the Apache Portable Runtime library on Unix platforms would allow local users read access to named shared memory segments, potentially revealing sensitive application data.

This issue does not affect non-Unix platforms, or builds with APR_USE_SHMEM_SHMGET=1 (apr.h)

Users are recommended to upgrade to APR version 1.7.5, which fixes this issue. (CVE-2023-49582)

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

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

Solution

Run 'yum update apr' to update your system.
