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 https://www.flexera.com/products/security/software-vulnerability-research/secunia-research Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200508-04 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.
