Debian DSA-1916-1 : kdelibs - insufficient input validation

high Nessus Plugin ID 44781

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Dan Kaminsky and Moxie Marlinspike discovered that kdelibs, core libraries from the official KDE release, does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

Solution

Upgrade the kdelibs packages.

For the oldstable distribution (etch), this problem has been fixed in version 4:3.5.5a.dfsg.1-8etch3.

Due to a bug in the archive system, the fix for the stable distribution (lenny), will be released as version 4:3.5.10.dfsg.1-0lenny3 once it is available.
