Background ========= Kiax is a graphical softphone supporting the IAX protocol (Inter Asterisk eXchange), which allows PC users to make VoIP calls to Asterisk servers. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/kiax < 0.8.5_p1 > = 0.8.5_p1 Description ========== The iax_net_read function in the iaxclient library fails to properly handle IAX2 packets with truncated full frames or mini-frames. These frames are detected in a length check but processed anyway, leading to buffer overflows. Impact ===== By sending a specially crafted IAX2 packet, an attacker could execute arbitrary code with the permissions of the user running Kiax. Workaround ========= There is no known workaround at this time. Resolution ========= All Kiax users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =net-misc/kiax-0.8.5_p1" References ========= [ 1 ] CVE-2006-2923 https://www.cve.org/CVERecord?id=CVE-2006-2923 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200606-30 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.
