Descriptions

The _ar_read_header function in archive_read_support_format_ar.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds stack read) via a crafted ar file.

La función lha_ar_read_header en archive_read_support_format_ar.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos provocar una denegación de servicio (lectura de pila fuera de rango) a través de un archivo ar manipulado.

A vulnerability was found in libarchive. A specially crafted AR archive could cause the application to read a single byte of application memory, potentially disclosing it to the attacker.
