lintian 1.23 and earlier removes the working directory even if it was not created by lintian, which may allow local users to delete arbitrary files or directories via a symlink attack.

Multiple format string 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 have an unspecified impact via vectors involving (1) check scripts and (2) the Lintian::Schedule module.

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.

Lintian 1.23.x through 1.23.28, 1.24.x through 1.24.2.1, and 2.x before 2.3.2 allows remote attackers to execute arbitrary commands via shell metacharacters in filename arguments.

Lintian before 2.5.12 allows remote attackers to gather information about the "host" system using crafted symlinks.
