The (1) kantiword (kantiword.sh) and (2) gantiword (gantiword.sh) scripts in antiword 0.35 and earlier allow local users to overwrite arbitrary files via a symlink attack on temporary (a) output and (b) error files.

Weakness

The product 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
Antiword Antiword 0.35 0.35
Antiword Antiword 0.32 0.32

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.
