Synopsis: Important: krb5 security and bug fix update
Issue date: 2010-11-30
CVE Names: CVE-2010-1323 CVE-2010-1324 CVE-2010-4020
Multiple checksum validation flaws were discovered in the MIT Kerberos
implementation. A remote attacker could use these flaws to tamper with
certain Kerberos protocol packets and, possibly, bypass authentication
or authorization mechanisms and escalate their privileges.
(CVE-2010-1323, CVE-2010-1324, CVE-2010-4020)
This update also fixes the following bug:
* When attempting to perform PKINIT pre-authentication, if the client
had more than one possible candidate certificate the client could fail
to select the certificate and key to use. This usually occurred if
certificate selection was configured to use the value of the keyUsage
extension, or if any of the candidate certificates did not contain a
subjectAltName extension. Consequently, the client attempted to perform
pre-authentication using a different (usually password-based) mechanism.
(BZ#644825)
After installing the updated packages, the krb5kdc daemon will be
restarted automatically.
