SUSE SLES12 Security Update : perl (SUSE-SU-2026:3540-1)

critical Nessus Plugin ID 334468

Synopsis

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

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3540-1 advisory.

- CVE-2026-8376: heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds (bsc#1266304).
- CVE-2026-12087: `Socket`'s `pack_ip_mreq_source()` can copy adjacent heap memory into the returned packed structure (bsc#1268349).
- CVE-2026-57432: an integer overflow in `S_measure_struct` leads to an out-of-bounds heap read in `pack` and `unpack` (bsc#1271372).

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 perl, perl-32bit, perl-base and / or perl-doc packages.
