Amazon Linux 2 Security Advisory: ALAS2-2025-2932
Advisory Released Date: 2025-07-30
Advisory Updated Date: 2025-07-30
Severity:
Medium
Issue Overview:
A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one' miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more sophisticated exploitation. (CVE-2025-5917)
