Detail
| The SIP channel driver in Asterisk Open Source 1.2.x before 1.2.34, 1.4.x before 1.4.26.1, 1.6.0.x before 1.6.0.12, and 1.6.1.x before 1.6.1.4; 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 1.3.0.3 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. |

| Id | Description |
|---|---|
| 56991 | Asterisk Multiple Function Maximum Width Handling Remote DoS Asterisk contains a flaw that may allow a remote denial of service. The issue is triggered when a malicious user forces invocation of sscanf() functions which do not specify a maximum width, and will result in loss of availability for the service. |
