Título:	SUSE: Security Advisory for krb5 (SUSE-SU-2015:0290-2)
Resumen:	The remote host is missing an update for the 'krb5'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'krb5' package(s) announced via the referenced advisory. Vulnerability Insight: MIT kerberos krb5 was updated to fix several security issues and bugs. Security issues fixed: CVE-2014-5351: The kadm5_randkey_principal_3 function in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) sent old keys in a response to a -randkey -keepold request, which allowed remote authenticated users to forge tickets by leveraging administrative access. CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after gss_process_context_token() is used to process a valid context deletion token, the caller was left with a security context handle containing a dangling pointer. Further uses of this handle would have resulted in use-after-free and double-free memory access violations. libgssrpc server applications such as kadmind were vulnerable as they can be instructed to call gss_process_context_token(). CVE-2014-9421: If the MIT krb5 kadmind daemon receives invalid XDR data from an authenticated user, it may have performed use-after-free and double-free memory access violations while cleaning up the partial deserialization results. Other libgssrpc server applications might also been vulnerable if they contain insufficiently defensive XDR functions. CVE-2014-9422: The MIT krb5 kadmind daemon incorrectly accepted authentications to two-component server principals whose first component is a left substring of 'kadmin' or whose realm is a left prefix of the default realm. CVE-2014-9423: libgssrpc applications including kadmind output four or eight bytes of uninitialized memory to the network as part of an unused 'handle' field in replies to clients. Bugs fixed: - Work around replay cache creation race (bnc#898439). Affected Software/OS: krb5 on SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Desktop 12 Solution: Please install the updated package(s). CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
