Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2196-1 advisory.

Update to version 5.3.6:

- CVE-2020-24371: lgc.c mishandles the interaction between barriers and the sweep phase, leading to a memory access violation involving collectgarbage (bsc#1175449)
- CVE-2020-24370: ldebug.c allows a negation overflow and segmentation fault in getlocal and setlocal (bsc#1175448)
- Long brackets with a huge number of '=' overflow some internal buffer arithmetic.

Tenable has extracted the preceding description block directly from the SUSE 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

Update the affected liblua5_3-5, liblua5_3-5-32bit, lua53 and / or lua53-devel packages.
