Amazon Linux 2 : (ALAS-2023-1936)

critical Nessus Plugin ID 171468

Language:

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1936 advisory.

- An out-of-bounds array read in the apr_time_exp*() functions was fixed in the Apache Portable Runtime 1.6.3 release (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch, and hence version 1.7.0 regressed compared to 1.6.3 and is vulnerable to the same issue. (CVE-2021-35940)

- Integer Overflow or Wraparound vulnerability in apr_encode functions of Apache Portable Runtime (APR) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable Runtime (APR) version 1.7.0. (CVE-2022-24963)

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

Solution

pkg_manager = 'yum'Run ' update apr' to update your system.
