SUSE Security Update: Security update for krb5 ______________________________________________________________________________ Announcement ID: SUSE-SU-2015:0290-1 Rating: important References: #897874 #898439 #912002 Cross-References: CVE-2014-5351 CVE-2014-5352 CVE-2014-9421 CVE-2014-9422 CVE-2014-9423 Affected Products: SUSE Linux Enterprise Software Development Kit 12 SUSE Linux Enterprise Server 12 SUSE Linux Enterprise Build System Kit 12 ______________________________________________________________________________ An update that fixes 5 vulnerabilities is now available. Description: 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). Patch Instructions: To install this SUSE Security Update use YaST online_update.
