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.

CVE-2025-5915 [HIGH] libarchive vulnerabilities
Title: libarchive vulnerabilities
Summary: Several security issues were fixed in libarchive.
It was discovered that libarchive incorrectly handled certain RAR archive
files. An attacker could possibly use this issue to execute arbitrary
code or cause a denial of service. (CVE-2025-5914)
It was discovered that libarchive incorrectly handled certain RAR archive
files. An attacker could possibly use this issue to read sensitive data
or cause a denial of service. (CVE-2025-5915)
It was discovered that libarchive incorrectly handled certain WARC
archive files. If a user or automated system were tricked into processing
a specially crafted WARC archive, an attacker could use this issue to
cause libarchive to crash, resulting in a denial of service.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
