Synopsis: Critical: openafs on SL5.x, SL6.x i386/x86_64
Issue date: 2013-07-24
CVE Numbers: CVE-2013-4134
CVE-2013-4135
--
OpenAFS uses Kerberos tickets to secure network traffic. For historical
reasons, it has only supported the DES encryption algorithm to encrypt these
tickets. The weakness of DES's 56 bit key space has long been known, however
it has recently become possible to use that weakness to cheaply (around $100)
and rapidly (approximately 23 hours) compromise a service's long term key. An
attacker must first obtain a ticket for the cell. They may then use a brute
force attack to compromise the cell's private service key. Once an attacker
has gained access to the service key, they can use this to impersonate any
user within the cell, including the super user, giving them access to all
administrative capabilities as well as all user data. Recovering the service
key from a DES encrypted ticket is an issue for any Kerberos service still
using DES (and especially so for realms which still have DES keys on their
ticket granting ticket). (CVE-2013-4134)
The -encrypt option to the 'vos' volume management command should cause it to
encrypt all data between client and server. However, in versions of OpenAFS
later than 1.6.0, it has no effect, and data is transmitted with integrity
protection only. In all versions of OpenAFS, vos -encrypt has no effect when
combined with the -localauth option. (CVE-2013-4135)
