Description:
A security issue has been reported in Asterisk, which can be exploited by malicious people to bypass certain security restrictions.
The security issue is caused due to a problem within the AEL (Asterisk Extension Language) when generating switch extensions. Depending on the extension, an attacker may be able to guess and dial a special number, which could allow him to e.g. listen to the voicemails of other users.
Solution:
Fixed in the SVN repository.
