Descriptions

Multiple directory traversal vulnerabilities in Lintian 1.23.x through 1.23.28, 1.24.x through 1.24.2.1, and 2.x before 2.3.2 allow remote attackers to overwrite arbitrary files or obtain sensitive information via vectors involving (1) control field names, (2) control field values, and (3) control files of patch systems.

Múltiples vulnerabilidades de salto de directorio en Lintian v1.23.x anterior a v1.23.28, v1.24.x anterior a v1.24.2.1, y v2.x anterior a v2.3.2 permite a atacantes remotos sobreescribir archivos a su elección u obtener información sensible a través de vectores que implican (1)nombres de los campos de control, (2)valores de los campos de control, y (3)archivos de control de los sistemas de revisión.

It was discovered that lintian did not correctly validate certain filenames when processing input. If a user or an automated system were tricked into running lintian on a specially crafted set of files, a remote attacker could execute arbitrary code with user privileges.
