See How to fix? for Debian:unstable relevant fixed versions and status.
Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, a stack buffer overflow in the H.323 ooTrace() trace-logging function can occur when unbounded vsprintf writes into a fixed 2048-byte buffer. A remote attacker may send a carefully crafted packet that causes the Asterisk process to crash. The chan_ooh323 addon channel driver must be explicitly compiled and installed, which is not the default, and its port must be publicly reachable. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.
