Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4179-1 advisory.

- CVE-2026-20337: Improper boundary checks for content in zip archive parser (bsc#1274597).
- CVE-2026-20338: invalid free due to bad ownership handling when merging ZIP catalogue records (bsc#1274598).
- CVE-2026-20339: integer overflow in the PESpin unpacker leads to undersized allocation and heap out-of- bounds write (bsc#1274599).
- CVE-2026-20345: out-of-bounds read/write via indexing error when converting GPT partition names (bsc#1274600).
- CVE-2026-20346: integer underflow when parsing malformed PDF hex strings causes a crash (bsc#1274601).
- CVE-2026-20347: integer overflow and undefined behavior when scanning malformed Mach-O files causes a crash (bsc#1274602).
- CVE-2026-20348: improper size handling in the XAR parser allows excessive allocation and scan-limit bypass (bsc#1274603).
- CVE-2026-46671: onenote_parser: Path traversal in `Parser:parse_notebook` allows reading files outside the notebook directory (bsc#1271922).
- CVE-2025-8088: rejects path separators in NTFS alternate data stream names to prevent extraction outside ClamAV's temporary scan directory on Windows.

Changes for clamav:

Update to 1.5.4:

* Fixed thread-safety issues in the clamd STATS command that could disclose process memory or crash the daemon while scans and STATS requests run concurrently. Also fixed partial socket-write handling used for large STATS responses.
* FreeBSD: Restored support for safe quarantine move and remove actions while preserving protection against source-path replacement races.
* Fixed an OpenSSL library-context leak in legacy hashing helpers when a requested message digest cannot be fetched, such as when the default provider is unavailable in a FIPS-enabled environment.
* Upgraded the Rust crossbeam-epoch dependency to resolve the RUSTSEC-2026-0204 advisory.

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.
