CVE-2014-5351 [LOW] Kerberos vulnerabilities
Title: Kerberos vulnerabilities
Summary: Several security issues were fixed in Kerberos.
It was discovered that Kerberos incorrectly sent old keys in response to a
-randkey -keepold request. An authenticated remote attacker could use this
issue to forge tickets by leveraging administrative access. This issue
only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu 14.04 LTS.
(CVE-2014-5351)
It was discovered that the libgssapi_krb5 library incorrectly processed
security context handles. A remote attacker could use this issue to cause
a denial of service, or possibly execute arbitrary code. (CVE-2014-5352)
Patrik Kis discovered that Kerberos incorrectly handled LDAP queries with
no results. An authenticated remote attacker could use this issue to cause
the KDC to crash, resulting in
