ZDI-CAN-13347: ISC BIND TKEY Query Integer Overflow Remote Code Execution Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of ISC BIND. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of TKEY queries. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the "bind" user.
