The tempname_ensure function in lib/routines.h in a2ps 4.14 and earlier, as used by the spy_user function and possibly other functions, allows local users to modify arbitrary files via a symlink attack on a temporary file.

Jakub Wilk found that a2ps, a tool to convert text and other types of files to PostScript, insecurely used a temporary file in spy_user(). A local attacker could use this flaw to perform a symbolic link attack to modify an arbitrary file accessible to the user running a2ps.
