Problembeschreibung

A number of vulnerabilities have been corrected in this Kerberos update: The rcp protocol would allow a server to instruct a client to write to arbitrary files outside of the current directory. The Kerberos-aware rcp could be abused to copy files from a malicious server (CAN-2004-0175). Gael Delalleau discovered an information disclosure vulnerability in the way some telnet clients handled messages from a server. This could be abused by a malicious telnet server to collect information from the environment of any victim connecting to the server using the Kerberos- aware telnet client (CAN-2005-0488). Daniel Wachdorf disovered that in error conditions that could occur in response to correctly-formatted client requests, the Kerberos 5 KDC may attempt to free uninitialized memory, which could cause the KDC to crash resulting in a Denial of Service (CAN-2005-1174). Daniel Wachdorf also discovered a single-byte heap overflow in the krb5_unparse_name() function that could, if successfully exploited, lead to a crash, resulting in a DoS. To trigger this flaw, an attacker would need to have control of a Kerberos realm that shares a cross- realm key with the target (CAN-2005-1175). Finally, a double-free flaw was discovered in the krb5_recvauth() routine which could be triggered by a remote unauthenticated attacker. This issue could potentially be exploited to allow for the execution of arbitrary code on a KDC. No exploit is currently known to exist (CAN-2005-1689). The updated packages have been patched to address this issue and Mandriva urges all users to upgrade to these packages as quickly as possible.
