Background ========== feh is an X11 image viewer aimed mostly at console users. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/feh < 2.18.3 >= 2.18.3 Description =========== Tobias Stoeckmann discovered it was possible to trigger an out-of-boundary heap write with the image viewer feh while receiving an IPC message. Impact ====== A remote attacker, pretending to be the E17 window manager, could possibly trigger an out-of-boundary heap write in feh while receiving an IPC message. This could result in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All feh users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/feh-2.18.3" References ========== [ 1 ] CVE-2017-7875 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-7875 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201707-08 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.
