Description Murray McAllister 2014-03-31 02:25:19 UTC

brian m. carlson reported that a2ps's fixps script does not invoke gs with the -dSAFER option. Running fixps on a malicious PostScript file could result in files being deleted or arbitrary commands being executed with the privileges of the user running fixps.

A possible patch from Debian is available from the Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?msg=12;filename=a2ps-4.14-1.3-nmu.diff;att=1;bug=742902
