Background ========== mpg123 is a real time audio player designed for the MPEG format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-sound/mpg123 < 0.59s-r11 >= 0.59s-r11 Description =========== In httpdget.c, a variable is assigned to the heap, and is supposed to receive a smaller allocation. As this variable was not terminated properly, strncpy() will overwrite the data assigned next in memory. Impact ====== By enticing a user to visit a malicious URL, an attacker could possibly execute arbitrary code with the rights of the user running mpg123. Workaround ========== There is no known workaround at this time. Resolution ========== All mpg123 users should update to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r11" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200607-01.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.
