hugin, as used on various operating systems including SUSE openSUSE 10.2 and 10.3, allows local users to overwrite arbitrary files via a symlink attack on the hugin_debug_optim_results.txt temporary file.

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
Opensuse Opensuse 10.2 (including) 10.2 (including)
Opensuse Opensuse 10.3 (including) 10.3 (including)
Hugin Ubuntu devel *
Hugin Ubuntu edgy *
Hugin Ubuntu feisty *
Hugin Ubuntu gutsy *

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.
