2020-06-30 CVE-2017-18922 It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow. Ubuntu_linux, Fedora, Libvncserver, Leap, Simatic_itc1500_firmware, Simatic_itc1500_pro_firmware, Simatic_itc1900_firmware, Simatic_itc1900_pro_firmware, Simatic_itc2200_firmware, Simatic_itc2200_pro_firmware 9.8
2020-06-17 CVE-2020-14401 An issue was discovered in LibVNCServer before 0.9.13. libvncserver/scale.c has a pixel_value integer overflow. Debian_linux, Libvncserver, Leap, Simatic_itc1500_firmware, Simatic_itc1500_pro_firmware, Simatic_itc1900_firmware, Simatic_itc1900_pro_firmware, Simatic_itc2200_firmware, Simatic_itc2200_pro_firmware 6.5
2020-11-27 CVE-2020-25708 A divide by zero issue was found to occur in libvncserver-0.9.12. A malicious client could use this flaw to send a specially crafted message that, when processed by the VNC server, would lead to a floating point exception, resulting in a denial of service. Libvncserver, Enterprise_linux 7.5
2018-02-19 CVE-2018-7225 An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets. Ubuntu_linux, Debian_linux, Libvncserver, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation 9.8
2016-12-31 CVE-2016-9942 Heap-based buffer overflow in ultra.c in LibVNCClient in LibVNCServer before 0.9.11 allows remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message with the Ultra type tile, such that the LZO payload decompressed length exceeds what is specified by the tile dimensions. Libvncserver 9.8
2016-12-31 CVE-2016-9941 Heap-based buffer overflow in rfbproto.c in LibVNCClient in LibVNCServer before 0.9.11 allows remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message containing a subrectangle outside of the client drawing area. Libvncserver 9.8
2020-06-17 CVE-2020-14400 ** DISPUTED ** An issue was discovered in LibVNCServer before 0.9.13. Byte-aligned data is accessed through uint16_t pointers in libvncserver/translate.c. NOTE: Third parties do not consider this to be a vulnerability as there is no known path of exploitation or cross of a trust boundary. Debian_linux, Libvncserver, Leap N/A
2020-06-17 CVE-2020-14399 ** DISPUTED ** An issue was discovered in LibVNCServer before 0.9.13. Byte-aligned data is accessed through uint32_t pointers in libvncclient/rfbproto.c. NOTE: there is reportedly "no trust boundary crossed." Debian_linux, Libvncserver, Leap N/A
2020-02-05 CVE-2010-5304 A NULL pointer dereference flaw was found in the way LibVNCServer before 0.9.9 handled certain ClientCutText message. A remote attacker could use this flaw to crash the VNC server by sending a specially crafted ClientCutText message from a VNC client. Fedora, Libvncserver N/A
