| CVE-2022-23967 | 1 Tightvnc | 1 Tightvnc | 2022-02-02 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2021-42785 | 1 Tightvnc | 1 Tightvnc | 2021-11-29 | 7.5 HIGH | 9.8 CRITICAL |
| Buffer Overflow vulnerability in tvnviewer.exe of TightVNC Viewer allows a remote attacker to execute arbitrary instructions via a crafted FramebufferUpdate packet from a VNC server. | |||||
| CVE-2019-15678 | 1 Tightvnc | 1 Tightvnc | 2020-12-09 | 7.5 HIGH | 9.8 CRITICAL |
| TightVNC code version 1.3.10 contains heap buffer overflow in rfbServerCutText handler, which can potentially result code execution.. This attack appear to be exploitable via network connectivity. | |||||
