Summary
The krb5_ldap_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors, related to the locked_check_p function. NOTE: the Berkeley DB vector is covered by CVE-2011-4151.

Summary
Red Hat Security Advisory: krb5 security update
Notes
Topic
Updated krb5 packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC).
Multiple NULL pointer dereference and assertion failure flaws were found
in the MIT Kerberos KDC when it was configured to use an LDAP (Lightweight
Directory Access Protocol) or Berkeley Database (Berkeley DB) back end. A
remote attacker could use these flaws to crash the KDC. (CVE-2011-1527,
CVE-2011-1528, CVE-2011-1529)
Red Hat would like to thank the MIT Kerberos project for reporting the
CVE-2011-1527 issue. Upstream acknowledges Andrej Ota as the original
reporter of CVE-2011-1527.
All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct these issues. After installing the updated
packages, the krb5kdc daemon will be restarted automatically.

Summary
Red Hat Security Advisory: krb5 security update
Notes
Topic
Updated krb5 packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC).
Multiple NULL pointer dereference and assertion failure flaws were found
in the MIT Kerberos KDC when it was configured to use an LDAP (Lightweight
Directory Access Protocol) or Berkeley Database (Berkeley DB) back end. A
remote attacker could use these flaws to crash the KDC. (CVE-2011-1527,
CVE-2011-1528, CVE-2011-1529)
Red Hat would like to thank the MIT Kerberos project for reporting the
CVE-2011-1527 issue. Upstream acknowledges Andrej Ota as the original
reporter of CVE-2011-1527.
All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct these issues. After installing the updated
packages, the krb5kdc daemon will be restarted automatically.

Vulnerability from csaf_redhat

Summary
Red Hat Security Advisory: krb5 security update
Notes
Topic
Updated krb5 packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC).
Multiple NULL pointer dereference and assertion failure flaws were found
in the MIT Kerberos KDC when it was configured to use an LDAP (Lightweight
Directory Access Protocol) or Berkeley Database (Berkeley DB) back end. A
remote attacker could use these flaws to crash the KDC. (CVE-2011-1527,
CVE-2011-1528, CVE-2011-1529)
Red Hat would like to thank the MIT Kerberos project for reporting the
CVE-2011-1527 issue. Upstream acknowledges Andrej Ota as the original
reporter of CVE-2011-1527.
All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct these issues. After installing the updated
packages, the krb5kdc daemon will be restarted automatically.
