Description Lubomir Kundrak 2007-11-06 17:54:41 UTC 
Description of problem:

Dvips uses insecure tmpnam() function to create files for temporary data while
converting a DVI file to laser jet printer format. A local attacker could
conduct a time-dependent attack by creating the files before dviljk uses them
which could possibly lead into information leak and would permit the attacker to
modify the processed data.

Additional info:

See URL filed for Gentoo report.
The attached file fixes this problem by using a secure temporary directory
together with other issues.
