  Date Alert Description
7.8 2009-08-12 CVE-2009-2726

The SIP channel driver in Asterisk Open Source 1.2.x before 1.2.34, 1.4.x before, 1.6.0.x before, and 1.6.1.x before; Asterisk Business Edition A.x.x, B.x.x before B.2.5.9, C.2.x before C.2.4.1, and C.3.x before C.3.1; and Asterisk Appliance s800i 1.2.x before does not use a maximum width when invoking sscanf style functions, which allows remote attackers to cause a denial of service (stack memory consumption) via SIP packets containing large sequences of ASCII decimal characters, as demonstrated via vectors related to (1) the CSeq value in a SIP header, (2) large Content-Length value, and (3) SDP.
