Arches, please test & mark stable: =net-misc/asterisk-1.8.2.20 =net-misc/asterisk-11.2.2 Target keywords: amd64 x86 Once installed with USE="samples" to gain default configuration files, please try to stop & start the daemon three times in sequence. Unless further test hardware is available, this is a suitable and complete test. amd64 stable x86 stable Updated existing GLSA draft. + 30 Mar 2013; Tony Vroon <chainsaw@gentoo.org> -asterisk-1.8.20.1.ebuild, + -asterisk-11.2.1.ebuild: + Remove vulnerable ebuilds after stabling, for security bug #463622. CVE-2013-2686 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2686): main/http.c in the HTTP server in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones does not properly restrict Content-Length values, which allows remote attackers to conduct stack-consumption attacks and cause a denial of service (daemon crash) via a crafted HTTP POST request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-5976. CVE-2013-2685 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2685): Stack-based buffer overflow in res/res_format_attr_h264.c in Asterisk Open Source 11.x before 11.2.2 allows remote attackers to execute arbitrary code via a long sprop-parameter-sets H.264 media attribute in a SIP Session Description Protocol (SDP) header. CVE-2013-2264 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2264): The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones exhibits different behavior for invalid INVITE, SUBSCRIBE, and REGISTER transactions depending on whether the user account exists, which allows remote attackers to enumerate account names by (1) reading HTTP status codes, (2) reading additional text in a 403 (aka Forbidden) response, or (3) observing whether certain retransmissions occur. This issue was resolved and addressed in GLSA 201401-15 at http://security.gentoo.org/glsa/glsa-201401-15.xml by GLSA coordinator Sergey Popov (pinkbyte). |
