VuXML IDDescription
a6986f0f-3ac0-11ee-9a88-206a8a720317krb5 -- Double-free in KDC TGS processing

The MIT krb5 Team reports:

When issuing a ticket for a TGS renew or validate request, copy only the server field from the outer part of the header ticket to the new ticket. Copying the whole structure causes the enc_part pointer to be aliased to the header ticket until krb5_encrypt_tkt_part() is called, resulting in a double-free if handle_authdata() fails..
