Description Tomas Hoger 2008-09-05 09:27:06 EDT
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-3903 to the following vulnerability:

Asterisk PBX 1.2 through 1.6 and Trixbox PBX 2.6.1, when running with
Digest authentication and authalwaysreject enabled, generates
different responses depending on whether or not a SIP username is
valid, which allows remote attackers to enumerate valid usernames.

Referenced advisory contains proposed patch, but there does not seem to be an official upstream advisory for this issue yet.
Comment 3 Jeffrey C. Ollie 2009-11-02 14:24:17 EST
I believe that this can be closed as 1.6.0.15 is the current version in F-10 and F-11+ are running 1.6.1.x.
