CVE-2025-5915
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se ha identificado una vulnerabilidad en la librería libarchive. Esta falla puede provocar una sobrelectura del búfer de memoria dinámica (heap buffer) debido a que el tamaño de un bloque de filtro puede exceder la ventana Lempel-Ziv-Storer-Schieber (LZSS). Esto significa que la librería podría intentar leer más allá del búfer de memoria asignado, lo que puede provocar un comportamiento impredecible del programa, fallos (denegación de servicio) o la divulgación de información confidencial de regiones de memoria adyacentes."
