A local attacker could use this flaw to perform a symbolic link attack to modify an arbitrary file accessible to the user running a2ps: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737385 The original report notes there are calls to tempname_ensure(). If any of those are found to be vulnerable, would they use the same CVE number, or require a different one?
