Background ========== SILC Server is a server for the Secure Internet Live Conferencing (SILC) protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/silc-server < 1.0.2-r1 >= 1.0.2-r1 Description =========== Frank Benkstein discovered a possible NULL pointer dereference in apps/silcd/command.c if a new channel is created without specifying a valid hmac or cipher algorithm name. Impact ====== A remote attacker could cause the server to crash, resulting in a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All SILC Server users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-im/silc-server-1.0.2-r1" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-12.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.
