Descriptions

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.

Info-ZIP UnZip 6.0 permite a atacantes remotos provocar una denegación de servicio (sobre lectura de buffer basado en memoria dinámica y caída de aplicación) o posiblemente ejecutar código arbitrario a través de un archivo ZIP protegido con contraseña manipulado, posiblemente relacionado con un valor de tamaño Extra-Field.

USN-2788-1 fixed vulnerabilities in unzip. One of the security patches caused a regression when extracting 0-byte files. This update fixes the problem.

If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code. Gustavo Grieco discovered that unzip incorrectly handled certain malformed archives.
