CVE-2012-1016 [MEDIUM] Kerberos vulnerabilities
Title: Kerberos vulnerabilities
Summary: Several security issues were fixed in Kerberos.
It was discovered that Kerberos incorrectly handled certain crafted Draft 9
requests. A remote attacker could use this issue to cause the daemon to
crash, resulting in a denial of service. This issue only affected Ubuntu
12.04 LTS. (CVE-2012-1016)
It was discovered that Kerberos incorrectly handled certain malformed
KRB5_PADATA_PK_AS_REQ AS-REQ requests. A remote attacker could use this
issue to cause the daemon to crash, resulting in a denial of service. This
issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1415)
It was discovered that Kerberos incorrectly handled certain crafted TGS-REQ
requests. A remote authenticated attacker could use this issue to cause the

krb5: denial of service flaws when handling padding length longer than the plaintext
MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session.
A buffer over-read flaw was found in the way MIT Kerberos handled certain requests. A remote, unauthenticated attacker who is able to inject packets into a client or server application's GSSAPI session could use this flaw to crash the application.

Discussion:
Created krb5 tracking bugs for this issue:
Affects: fedora-all [bug 1116181]
---
There are two distinct flaws in krb5:
CVE-2014-4341: Affects all shipped versions of krb5 package.
CVE-2014-4342: Affects only krb5-1.7 and later.
Hence it makes more sense to split this bug into two parts.
We will use this flaw for CVE-2014-4341.
