Debian Security Advisory

DSA-2031-1 krb5 -- use-after-free

Date Reported:

11 Apr 2010

Affected Packages:

krb5

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 567052.
In Mitre's CVE dictionary: CVE-2010-0629.

More information:

Sol Jerome discovered that kadmind service in krb5, a system for authenticating users and services on a network, allows remote authenticated users to cause a denial of service (daemon crash) via a request from a kadmin client that sends an invalid API version number.

For the stable distribution (lenny), this problem has been fixed in version 1.6.dfsg.4~beta1-5lenny3.

The testing distribution (squeeze), and the unstable distribution (sid) are not affected by this issue.

We recommend that you upgrade your krb5 package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
