|Bugzilla:||838012: CVE-2012-1015 krb5: KDC daemon crash via free() of an uninitialized pointer|
The MITRE CVE dictionary describes this issue as:
The kdc_handle_protected_negotiation function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x, 1.9.x before 1.9.5, and 1.10.x before 1.10.3 attempts to calculate a checksum before verifying that the key type is appropriate for a checksum, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer free, heap memory corruption, and daemon crash) via a crafted AS-REQ request.
Not vulnerable. This issue did not affect the versions of krb5 as shipped with Red Hat Enterprise Linux 5.
