# Security update for libarchive
Announcement ID: SUSE-SU-2026:3429-1
Release Date: 2026-07-30T11:18:19Z
Rating: moderate
References:
* bsc#1254340
* bsc#1254341
* bsc#1260998
* bsc#1261002
* bsc#1261003
Affected Products:
* Basesystem Module 15-SP7
* Development Tools Module 15-SP7
* openSUSE Leap 15.6
* SUSE Linux Enterprise Desktop 15 SP7
* SUSE Linux Enterprise Real Time 15 SP7
* SUSE Linux Enterprise Server 15 SP7
* SUSE Linux Enterprise Server for SAP Applications 15 SP7
An update that has five security fixes can now be installed.
## Description:
This update for libarchive fixes the following issues:
* 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).
* Incorrect pointer handling for RAR5 files declaring over 8192 filters can
lead to excessive resource usage and denial of service (bsc#1261002).
## Patch Instructions:
To install this SUSE update use the SUSE recommended installation methods like
YaST online_update or "zypper patch".
