Background ========== Netpbm is a package of 220 graphics programs and a programming library, including pnmtopng, a tool to convert PNM image files to the PNG format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/netpbm < 10.29 >= 10.29 Description =========== RedHat reported that pnmtopng is vulnerable to a buffer overflow. Impact ====== An attacker could craft a malicious PNM file and entice a user to run pnmtopng on it, potentially resulting in the execution of arbitrary code with the permissions of the user running pnmtopng. 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-10.29" References ========== [ 1 ] CAN-2005-2978 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2978 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200510-18.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.
