high Nessus Plugin ID 334781

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3548-1 advisory.

Security issues fixed:

- CVE-2026-0864: improper handling of line-ending characters can lead to configuration file injection when the `configparser` module is used (bsc#1269066).
- CVE-2026-3276: quadratic complexity in `unicodedata.normalize()` can lead to DoS when processing specially crafted Unicode input (bsc#1267581).
- CVE-2026-4360: in the `Tarfile.extract()` function, the filter parameter is not passed properly when extracting hardlinks (bsc#1269959).
- CVE-2026-7210: `xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash- flooding protection (bsc#1264962).
- CVE-2026-7774: `tarfile.data_filter` path traversal bypass allows writing outside the extraction directory (bsc#1267821).
- CVE-2026-8328: `ftpcp()` does not use actual peer address and trusts server-supplied PASV host address (bsc#1265268).
- CVE-2026-11940: tarfile extraction filter bypass via a crafted archive allows escaping the destination directory and enables arbitrary file reads and writes (bsc#1268977).
- CVE-2026-11972: infinite loop due to improper EOF handling in the tarfile module streaming mode can lead to DoS (bsc#1269788).
- CVE-2026-15308: incremental `HTMLParser` allows CPU-exhaustion DoS via repeated unterminated markup declarations (bsc#1271192).

Non security issue fixed:

- Improve testing for the support of `IPPROTO_UDPLITE`, which could be not present although header files are (bsc#1268375).

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.
