Descriptions

The process_extra function in libarchive before 3.2.0 uses the size field and a signed number in an offset, which allows remote attackers to cause a denial of service (crash) via a crafted zip file.

La función process_extra en libarchive en versiones anteriores a 3.2.0 utiliza el campo de tamaño y un número con signo en un desplazamiento, lo que permite a atacantes remotos provocar una denegación de servicio (caída) a través de un archivo zip manipulado.

A vulnerability was found in libarchive. A specially crafted ZIP file could cause a few bytes of application memory in a 256-byte region to be disclosed.
