kerberos - cryptographic weakness
| Package(s): | kerberos, heimdal, openafs |
CVE #(s): | CAN-2003-0138
CAN-2003-0139
|
| Created: | March 26, 2003 |
Updated: | May 27, 2003 |
| Description: |
Version 4 of the Kerberos protocol contains a cryptographic weakness which enables a chosen-plaintext attack. A suitably equipped attacker can impersonate any principal in the realm. Another weakness allows the creation of false Kerberos tickets. Given the weaknesses in the cryptography, cross-realm authentication cannot be performed in a secure way.
OpenAFS
kaserver implements version 4 of the Kerberos protocol, and therefore
is also vulnerable. |
