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 https://www.cve.org/CVERecord?id=CAN-2005-2978 Availability =========== This GLSA and anyupdates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200510-18 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.
