Detailsinfo

A vulnerability was found in Digium Asterisk 12.0.0 (Communications System) and classified as critical. This issue affects some unknown processing of the file main/http.c of the component Cookie Handler. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

main/http.c in Asterisk Open Source 1.8.x before 1.8.26.1, 11.8.x before 11.8.1, and 12.1.x before 12.1.1, and Certified Asterisk 1.8.x before 1.8.15-cert5 and 11.6 before 11.6-cert2, allows remote attackers to cause a denial of service (stack consumption) and possibly execute arbitrary code via an HTTP request with a large number of Cookie headers.

The weakness was released 03/10/2014 by Lucas Molas and Dr. Manuel Sadosky as AST-2014-001 as confirmed advisory (Website). The advisory is shared at downloads.asterisk.org.
