Description of problem:
The function gettext() in ps.c is vulnerable to a buffer overflow condition,
because it copies characters from input file to a fixed-sized array text.
Version-Release number of selected component (if applicable):
With specially crafted files looking like either of those below this paragraph.
(Replace ... with something a bit longer than PSLINELENGTH (256), so it

on functio return)
Alternatively use exploit attached to original advisory, which connects to
a TCP socket and opens a shell.
Ggv and kghostview seem not to contain the affected code.
