Description Bruno Buss 2009-01-09 12:31:40 UTC

"IAX2 provides a different response during authentication when a user does not exist, as compared to when the password is merely wrong. This allows an attacker to scan a host to find specific users on which to concentrate password cracking attempts."

Bump to 1.2.31 ou just apply this patch:

Arch target keywords:
~alpha amd64 ~hppa ~ppc sparc x86
