Detail
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. For the stable distribution (etch), this problem has been fixed in version 1.2.13~dfsg-2etch4. For the unstable distribution (sid), this problem has been fixed in version 1.4.19.1~dfsg-1. We recommend that you upgrade your asterisk packages. |
