CVE-2025-5917
Full vulnerability record from the local CVENow database.
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.

"value": "Se ha identificado una vulnerabilidad en la librería libarchive. Esta falla implica un error de cálculo de un byte al gestionar prefijos y sufijos de nombres de archivo. Esto puede provocar un desbordamiento de escritura de 1 byte. Aunque aparentemente leve, este desbordamiento puede corromper la memoria adyacente, provocando un comportamiento impredecible del programa, bloqueos o, en circunstancias específicas, podría utilizarse como base para una explotación más sofisticada."
