CVE-2007-5936
First published: Tue Nov 06 2007(Updated: )
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.
