An information disclosure flaw was found in mod_jk, the Tomcat Connector
module for Apache. If a buggy client included the βContent-Lengthβ header
without providing request body data, or if a client sent repeated
requests very quickly, one client could obtain a response intended for
another client.
The oldstable distribution (etch), this problem has been fixed in
version 1:1.2.18-3etch2.
For the stable distribution (lenny), this problem has been fixed in
version 1:1.2.26-2+lenny1.
For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1:1.2.26-2.1.
We recommend that you upgrade your libapache-mod-jk packages.
