Summary

libarchive security update

Details

is an open-source BSD-licensed C programming library that provides streaming access to a variety of different archive formats, including tar, cpio, pax, zip, and ISO9660 images. The distribution also includes bsdtar and bsdcpio, full-featured implementations of tar and cpio that use .

Security Fix(es):

A flaw was found in libarchive. An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.(CVE-2026-17591)
