Amazon Linux 2 : apr, apr-devel (ALAS-2023-1936)

critical Nessus Plugin ID 171468

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_base64 functions of Apache Portable Runtime Utility (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-24963)

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

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