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)

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.
