Severity: high (CVSS 7.5 v2.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 4.3% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2006-06-07 · updated 2026-06-16
Weakness: CWE-119

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.

Affected products

Digium Asterisk: 1.0.7, 1.0.8, 1.0.9, 1.0.10, 1.2.0_beta1, 1.2.0_beta2 (+3)
