Amazon Linux 2 : gsl (ALAS-2023-2255)

medium Nessus Plugin ID 181710

Language:

Synopsis

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

Description

The version of gsl installed on the remote host is prior to 1.15-13. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2255 advisory.

A buffer overflow can occur when calculating the quantile value using the Statistics Library of GSL (GNU Scientific Library), versions 2.5 and 2.6. Processing a maliciously crafted input data for gsl_stats_quantile_from_sorted_data of the library may lead to unexpected application termination or arbitrary code execution. (CVE-2020-35357)

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 gsl' to update your system.
