CVE-2013-1418 Kerberos allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request when multiple realms are configured.
CVE-2014-5351 Kerberos sends old keys in a response to a -randkey
-keepold request, which allows remote authenticated users to forge tickets by leveraging administrative access.
CVE-2014-5353 When the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.
CVE-2014-5355 Kerberos expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character,
CVE-2016-3119 Kerberos allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal.
CVE-2016-3120 Kerberos allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request.
For Debian 7 'Wheezy', these problems have been fixed in version 1.10.1 dfsg-5 deb7u9.
We recommend that you upgrade your krb5 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
