The remote Mandrake Linux host is missing one or more security
A number of vulnerabilities have been corrected in this Kerberos
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
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 (CVE-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 (CVE-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 (CVE-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
The updated packages have been patched to address this issue and
Mandriva urges all users to upgrade to these packages as quickly as
