The manpage states that: mech_type Object ID of desired mechanism. Supply GSS_C_NO_OID to obtain an implementation specific default So sending in GSS_C_NO_OID as mech_type should be allowed. >How-To-Repeat: Issue a gss_init_sec_context() call with the mech_type argument being GSS_C_NO_OID. Then wait for the segfault. >Fix: Patch can be found at: http://www.pvv.ntnu.no/~eirikald/patches/gssapi_mech_type_NO_OID.patch >Release-Note: >Audit-Trail: >Unformatted:
