A vulnerability, which was classified as critical, has been found in Digium Asterisk 1.4.44/1.6.2.23/1.8.10.1/10.2.1 (Communications System). Affected by this issue is the function milliwatt_generate of the file apps/app_milliwatt.c. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. CVE summarizes:

Stack-based buffer overflow in the milliwatt_generate function in the Miliwatt application in Asterisk 1.4.x before 1.4.44, 1.6.x before 1.6.2.23, 1.8.x before 1.8.10.1, and 10.x before 10.2.1, when the o option is used and the internal_timing option is off, allows remote attackers to cause a denial of service (application crash) via a large number of samples in an audio packet.

The weakness was shared 03/15/2012 by Russell Bryant (Website). The advisory is shared for download at downloads.asterisk.org. This vulnerability is handled as CVE-2012-1183 since 02/14/2012. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 58550 (Fedora 16 : asterisk-1.8.10.1-1.fc16 (2012-4318)), which helps to determine the existence of the flaw in a target environment.
