Multiple buffer overflows in dvi2xx.c in dviljk in teTeX and TeXlive 2007 and earlier might allow user-assisted attackers to execute arbitrary code via a crafted DVI input file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
