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

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.

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)
