CVE-2025-5917

Estado: ModificadaMedia (5)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
