SUSE SLES15 / openSUSE 15 Security Update : python39 (SUSE-SU-2024:1009-1)

high Nessus Plugin ID 192649

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1009-1 advisory.

 - libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)

 - An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances.
 (CVE-2023-6597)

 - An issue was found in the CPython `zipfile` module affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. (CVE-2024-0450)

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 packages.
