Background ========= The JPEG library is able to load, handle and manipulate images in the JPEG format. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/jpeg < 6b-r7 > = 6b-r7 Description ========== Tavis Ormandy of the Gentoo Linux Auditing Team discovered that the vulnerable JPEG library ebuilds compile JPEG without the --maxmem feature which is not recommended. Impact ===== By enticing a user to load a specially crafted JPEG image file an attacker could cause a Denial of Service, due to memory exhaustion. Workaround ========= There is no known workaround at this time. Resolution ========= JPEG users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =media-libs/jpeg-6b-r7" Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200606-11 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.
