DSA-273-1 krb4 -- Cryptographic weakness

Debian Security Advisory

DSA-273-1 krb4 -- Cryptographic weakness

Date Reported:

28 Mar 2003

Affected Packages:

krb4

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2003-0138, CVE-2003-0139.
CERT's vulnerabilities, advisories and incident notes: VU#623217, VU#442569.

More information:

A cryptographic weakness in version 4 of the Kerberos protocol allows an attacker to use a chosen-plaintext attack to impersonate any principal in a realm. Additional cryptographic weaknesses in the krb4 implementation permit the use of cut-and-paste attacks to fabricate krb4 tickets for unauthorized client principals if triple-DES keys are used to key krb4 services. These attacks can subvert a site's entire Kerberos authentication infrastructure.

For the stable distribution (woody) this problem has been fixed in version 1.1-8-2.3.

For the old stable distribution (potato) this problem has been fixed in version 1.0-2.3.

For the unstable distribution (sid) this problem has been fixed in version 1.2.2-1.

We recommend that you upgrade your krb4 packages immediately.

Fixed in:

Debian GNU/Linux 2.2 (potato)
