Debian DSA-1563-1 : asterisk - programming error

Medium Nessus Plugin ID 32125


The remote Debian host is missing a security-related update.


Joel R. Voss discovered that the IAX2 module of Asterisk, a free software PBX and telephony toolkit performs insufficient validation of IAX2 protocol messages, which may lead to denial of service.


Upgrade the asterisk packages.

For the stable distribution (etch), this problem has been fixed in version 1.2.13~dfsg-2etch4.
