CentOS Linux 8 [TuxCare] Security Update: python2 / python2-debug / python2-devel / python2-libs / etc Multiple Vulnerabilities (CENTOS-STREAM8:CLSA-2026:1790075259)

high Nessus Plugin ID 352443

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1790075259 advisory.

 - When using the tarfile module with a file opened in streaming mode (mode=r|) the tarfile module did not properly handle EOF, making archive parsing take exponentially longer. (CVE-2026-11972)

 - bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data. (CVE-2026-9669)

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 based on the guidance in TuxCare advisory CENTOS-STREAM8:CLSA-2026:1790075259.
