A ghostscript package fixing a command execution vulnerability is now available.
GNU Ghostscript is an interpreter for the PostScript language, and is often used when printing to printers that do not have their own built-in PostScript interpreter. A flaw has been discovered in the way Ghostscript validates some PostScript commands. This flaw allows an attacker to force commands to be executed by a print spooler by submitting a malicious print job. Note that using the -dSAFER option is not sufficient to prevent command execution. Users of Ghostscript are advised to upgrade to these updated packages, which are not vulnerable to this issue.
