Several vulnerabilities were discovered in krb5, the MIT implementation of Kerberos. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2014-4341 An unauthenticated remote attacker with the ability to inject packets into a legitimately established GSSAPI application session can cause a program crash due to invalid memory references when attempting to read beyond the end of a buffer. CVE-2014-4342 An unauthenticated remote attacker with the ability to inject packets into a legitimately established GSSAPI application session can cause a program crash due to invalid memory references when reading beyond the end of a buffer or by causing a null pointer dereference. CVE-2014-4343 An unauthenticated remote attacker with the ability to spoof packets appearing to be from a GSSAPI acceptor can cause a double-free condition in GSSAPI initiators which are using the SPNEGO mechanism, by returning a different underlying mechanism than was proposed by the initiator. A remote attacker could exploit this flaw to cause an application crash or potentially execute arbitrary code. CVE-2014-4344 An unauthenticated or partially authenticated remote attacker can cause a NULL dereference and application crash during a SPNEGO negotiation by sending an empty token as the second or later context token from initiator to acceptor. CVE-2014-4345 When kadmind is configured to use LDAP for the KDC database, an authenticated remote attacker can cause it to perform an out-of-bounds write .
