SUSE SLES12 Security Update : libarchive (SUSE-SU-2026:3587-1)

medium Nessus Plugin ID 335096

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2026:3587-1 advisory.

- creating temporary files in the current working directory instead of the target directory can lead to file creation failures when the working directory is not writable (bsc#1254340).
- file descriptor leak in the mtree parser cleanup path could lead to file descriptor exhaustion and denial of service (bsc#1261003).
- NULL pointer dereference in archive_acl_from_text_w() could lead to a segmentation fault (bsc#1260998).
- reading from an invalid index when buffer size is smaller than H_LEVEL_OFFSET can lead to an out-of- bounds buffer overrun (bsc#1254341).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libarchive-devel and / or libarchive13 packages.
