Security bump bug #339866.  Add double blocker to heimdal bug #339143.

On a side note, we can remove all patches in ${FILESDIR} except CVE-2010-1322.
Comment 4 Paul B. Henson 2010-10-21 22:36:51 UTC
Is someone going to add this to portage and get it stabilized? The current stable version is still vulnerable to this security issue.

Comment 5 GLSAMaker/CVETool Bot gentoo-dev 2010-10-23 14:04:52 UTC
CVE-2010-1322 (
  The merge_authdata function in kdc_authdata.c in the Key Distribution Center
  (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x before 1.8.4 does not properly
  manage an index into an authorization-data list, which allows remote
  attackers to cause a denial of service (daemon crash), or possibly obtain
  sensitive information, spoof authorization, or execute arbitrary code, via a
  TGS request, as demonstrated by a request from a Windows Active Directory

Any thoughts on getting this security fix marked stable?

Arches, please test and mark stable:

Seems to build just fine on SPARC, but no tests to run though.

amd64 done. Thanks Agostino
Comment 16 Alex Buell 2010-11-26 17:07:18 UTC
Retested 1.8.3-r1 as someone said they'd added tests to it. No sign of the tests. Perhaps another time but I didn't seen any problems.

Thanks, folks.

GLSA Vote: yes.
Comment 19 Dustin Polke 2010-11-27 18:21:51 UTC
Make this bug depend on #328467 as keyutils fails to merge on sparc right now.

Added to pending glsa request.
