| 2022-12-28 18:14:55 | In TightVNC 1.3.10, there is an integer signedness error and resultant heap-based buffer overflow in InitialiseRFBConnection in rfbproto.c (for the vncviewer component). There is no check on the size given to malloc, e.g., -1 is accepted. This allocates a chunk of size zero, which will give a heap pointer. However, one can send 0xffffffff bytes of data, which can have a DoS impact or lead to remote code execution. | ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2019-15679.
