Affected: AlmaLinux:9: bsdtar, AlmaLinux:9: libarchive, AlmaLinux:9: libarchive-devel

The libarchive programming library can create and read several different streaming archive formats, including GNU tar, cpio, and ISO 9660 CD-ROM images. Libarchive is used notably in the bsdtar utility, scripting language bindings such as python-libarchive, and several popular desktop file managers.

Security Fix(es):

* libarchive: Double free at archive_read_format_rar_seek_data() in archive_read_support_format_rar.c (CVE-2025-5914)

Affected: Alpaquita:23: libarchive, Alpaquita:stream: libarchive

A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.

Affected: openEuler:24.03-LTS-SP1: libarchive

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 vulnerability was found in libarchive up to 3.7.x (File Compression Software). It has been classified as critical.CWE is classifying the issue as CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.This is going to have an impact on confidentiality, integrity, and availability.Upgrading to version 3.8.0 eliminates this vulnerability.(CVE-2025-5914)

A vulnerability was found in libarchive up to 3.7.x (File Compression Software). It has been declared as critical.The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().As an impact it is known to affect confidentiality, integrity, and availability.Upgrading to version 3.8.0 eliminates this vulnerability.(CVE-2025-5915)
