Dan Rosenberg found a buffer overflow flaw in the way TeX text formatting system processed virtual font files. If a user was tricked into processing a specially-crafted typesetter-independent .dvi (DeVice Independent) file, it could lead to dvips executable crash or, potentially, to arbitrary code execution with the privileges of the user running dvips.

Integer overflow in the predospecial function in dospecial.c in dvips in (1) TeX Live and (2) teTeX might allow user-assisted remote attackers to execute arbitrary code via a crafted DVI file that triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.

An integer overflow was found in the way TeX text formatting system processed special commands. If a user was tricked into processing a specially-crafted typesetter-independent .dvi (DeVice Independent) file, it could lead to dvips executable crash or, potentially, to arbitrary code execution with the privileges of the user running dvips. Different vulnerability than CVE-2010-0739.

Dan Rosenberg reported multiple instances of an array index error in the way TeX text formatting system translated typesetter-independent .dvi (DeVice Independent) files into their Portable Network Graphics (PNG) alternatives. If a user was tricked into translation of a specially-crafted DVI file(s) into its PNG equivalent(s), it could lead to dvipng executable crash.
