Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2007-05-01 12:38:38 UTC 
Description:
A vulnerability has been reported in BIND, which can be exploited by malicious people to cause a DoS (Denial of Service).
 
 The vulnerability is caused due to an error when invoking the "query_addsoa()" function. This can be exploited to cause the nameserver to exit by sending a specially crafted sequence of queries.
 
 Successful exploitation requires that "recursion" is enabled.
 
 The vulnerability is reported in BIND version 9.4.0, and BIND versions 9.5.0a1, 9.5.0a2, and 9.5.0a3.

Solution:
Update to BIND 9.4.1.
Comment 1 Konstantin Arkhipov (RETIRED) gentoo-dev 2007-05-01 13:23:44 UTC 
bind and bind-tools bumped to 9.4.1.
Comment 2 Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2007-05-01 14:36:55 UTC 
Thx Konstantin.

Closing with NO GLSA since 9.4 is not stable yet.
