SUSE SLES15 Security Update : python (SUSE-SU-2026:2387-1)

critical Nessus Plugin ID 321027

Synopsis

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

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2387-1 advisory.

 This update for python fixes the following issues

 - CVE-2026-1703: files may be extracted outside the installation directory when installing and extracting maliciously crafted wheel archives (bsc#1257599).
 - CVE-2026-3219: pip doesn't reject concatenated ZIP (bsc#1262429).
 - CVE-2026-4786: Incomplete mitigation of %action expansion for command injection to webbrowser.open() (bsc#1262319).
 - CVE-2026-6019: BaseCookie.js_output() does not neutralize embedded characters (bsc#1262654).
 - CVE-2026-6100: arbitrary code execution or information disclosure via use-after-free in decompression modules (bsc#1262098).
 - CVE-2026-6357: pip self-update functionality can import newly installed modules after wheel installation (bsc#1263442).

 Changes for python:

 - For SLE-12-SP1 use vendored libffi (bsc#1261652). We have libffi4.so from SP3 only.

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 packages.
