From secunia at $URL: Description Two vulnerabilities have been reported in Kerberos, which can be exploited by malicious people to potentially compromise a vulnerable system. 1) An error within the "kdc_handle_protected_negotiation()" function (src/kdc/kdc_util.c) when creating a checksum does not properly verify the key type and can be exploited to free an uninitialized pointer via a specially crafted AS-REQ. This vulnerability is reported in krb5-1.8 and later only. 2) An uninitialized pointer dereference error within the "finish_process_as_req()" function (src/kdc/do_as_req.c) can be exploited to corrupt the memory by sending a specially crafted AS-REQ. This vulnerability is reported in krb5-1.10 and later only. Successful exploitation of these vulnerabilities may allow execution of arbitrary code. Solution Apply the patch (fixes are scheduled for the upcoming release of krb5-1.10.3 and krb5-1.9.5).

But please note that > =app-crypt/mit-krb5-1.10.2-r1 has additional keyword/stabilization > requirements - see bug #412489. 1.10 never had stable keyword, so no need to stabilize here and cause delay because of missing keywords. We stabilize only 1.9. Arches, please test and mark stable: =app-crypt/mit-krb5-appl-1.9.4-r1 Target keywords : "alpha amd64 arm hppa ia64 ppc ppc64 s390 sh sparc x86"

Stable for HPPA.
CVE-2012-1015 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1015): 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. CVE-2012-1014 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1014): The process_as_req function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x before 1.10.3 does not initialize a certain structure member, which allows remote attackers to cause a denial of service (uninitialized pointer dereference and daemon crash) or possibly execute arbitrary code via a malformed AS-REQ request.
