Common Vulnerabilities and Exposures assigned an identifier CVE-2013-6800 to the following vulnerability: Name: CVE-2013-6800 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-6800 Assigned: 20131115 Reference: http://krbdev.mit.edu/rt/Ticket/Display.html?id=7757 Reference: https://github.com/krb5/krb5/commit/c2ccf4197f697c4ff143b8a786acdd875e70a89d An unspecified third-party database module for the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request, a different vulnerability than CVE-2013-1418.
Created krb5 tracking bugs for this issue: Affects: fedora-all [bug 1031501]
This has a different identifier from CVE-2013-1418, but points to the same patch. Is there anything to update in the packaging here beyond what we already did for 1418?
No. I'm not sure why they split this other than the code looks slightly different but the fix is identical, and one is in 1.10.x and other 1.12. I'm actually at a complete loss as to why MITRE did this. As far as I'm concerned, this is CVE-2013-1418 (or bug #1026942).
Okay, then. I'll see if I can add this to the changelogs in source control, so that if/when we push other updates it'll show up there. Thanks!
Yeah, I think for some reason that this is for 1.10.x and the other is for 1.11 (which makes no sense as the code is so similar). I guess mention it but I'm quite certain these two CVEs should be one.
Apparently, split was triggered by this wording in the upstream RT / commit: *A related* but more minor vulnerability requires authentication to exploit, and is only present if a third-party KDC database module can dereference a null pointer under certain conditions.
Note: This issue can be triggered only if multiple realms are served from one KDC Statement: (none)
IssueDescription: It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer. A remote, unauthenticated attacker could use this flaw to crash the KDC using a specially crafted request.
