CVE-2006-2898 is a high-severity memory corruption vulnerability in Digium Asterisk, published on 7 Jun 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The IAX2 channel driver (chan_iax2) for Asterisk 1.2.x before 1.2.9 and 1.0.x before 1.0.11 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via truncated IAX 2 (IAX2) video frames, which bypasses a length check and leads to a buffer overflow involving negative length check. NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable.
