Description Murray McAllister 2014-03-10 20:53:48 EDT

Jakub Wilk discovered that perltidy's make_temporary_filename() function insecurely created temporary files via the use of the tmpnam() function. A local attacker could use this flaw to perform a symbolic link attack.

Fix from Don Armstrong: http://git.donarmstrong.com/?p=perltidy.git;a=blob;f=debian/patches/fix_insecure_tmpnam_usage_740670
