CWEhttps://cwe.mitre.org/data/definitions/59.html

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 0.32 (including) 0.32 (including)
Antiword Antiword 0.35 (including) 0.35 (including)
Antiword Ubuntu dapper *
Antiword Ubuntu devel *
Antiword Ubuntu edgy *
Antiword Ubuntu feisty *

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.
