Description:
A vulnerability and a security issue have been reported in Comix, which can be exploited by malicious, local users to cause a DoS (Denial of Service), and by malicious people to compromise a user's system.
1) An error exists while verifying filenames when executing the rar, unrar, or jpegtran programs. This can be exploited to execute arbitrary commands via a file containing shell metacharacters within the filename.
2) An error exists in the comix and comicthumb scripts when handling temporary files. This can be exploited to deny other users access to the application by creating a temporary directory with specific permissions.
The vulnerability and security issue are reported in version 3.6.4. Other versions may also be affected.
Solution:
Do not open untrusted files using Comix.
Restrict local access to trusted users only.
Provided and/or discovered by:
Reported by hhaamu in a Debian bug report.
