CentOS Errata and Security Advisory CESA-2007:1027
TeTeX is an implementation of TeX. TeX takes a text file and a set of formatting commands as input, and creates a typesetter-independent DeVice Independent (dvi) file as output.
Alin Rad Pop discovered several flaws in the handling of PDF files. An attacker could create a malicious PDF file that would cause TeTeX to crash or potentially execute arbitrary code when opened. (CVE-2007-4352, CVE-2007-5392, CVE-2007-5393)
A flaw was found in the t1lib library, used in the handling of Type 1 fonts. An attacker could create a malicious file that would cause TeTeX to crash, or potentially execute arbitrary code when opened. (CVE-2007-4033)
Users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
