The internal_dump function in Mathopd before 1.5p5, and 1.6x before 1.6b6 BETA, when Mathopd is running with the -n option, allows local users to overwrite arbitrary files via a symlink attack on dump files that are triggered by a SIGWINCH signal.

Weakness

The software attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
Mathopd Mathopd * *
Mathopd Mathopd 1.6 1.6

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
