Background ========== Netpbm is a package of 220 graphics programs and a programming libraries, including pstopnm. pstopnm is a tool which converts PostScript files to PNM image files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/netpbm < 10.28 >= 10.28 Description =========== Max Vozeler reported that pstopnm calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option, to convert a PostScript file into a PBM, PGM, or PNM file. Impact ====== An attacker could craft a malicious PostScript file and entice a user to run pstopnm on it, resulting in the execution of arbitrary commands with the permissions of the user running pstopnm. Workaround ========== There is no known workaround at this time. Resolution ========== All Netpbm users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/netpbm-10.28" References ========== [ 1 ] Secunia Advisory SA16184 http://secunia.com/advisories/16184/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-04.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
