TIMELINE

Jun 9 Published (CNA: redhat)
Aug 21 RESCORED — CVE-2025-5917 (libarchive). CVSS 2.8 → 5 (NVD).
Description
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. This bug affects libarchive versions prior to 3.8.0.
