Description:
A vulnerability has been reported in Asterisk, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the SIP (Session Initiation Protocol) implementation when handling certain SIP requests. This can be exploited by sending a specially crafted SIP request, which causes a buffer overflow.
Successful exploitation doesn't requires prior authentication and may allow execution of arbitrary code with "root" privileges.
Solution:
The vendor issued an updated CVS version on 15th of August 2003.
