|---|---|---|---|---|---|
| CVE-2006-1652 | 1 Ultravnc | 2 Tabbed Viewer, Vnc Viewer | 2018-10-18 | 9.0 HIGH | N/A |
| Multiple buffer overflows in (a) UltraVNC (aka Ultr@VNC) 1.0.1 and earlier and (b) tabbed_viewer 1.29 (1) allow user-assisted remote attackers to execute arbitrary code via a malicious server that sends a long string to a client that connects on TCP port 5900, which triggers an overflow in Log::ReallyPrint; and (2) allow remote attackers to cause a denial of service (server crash) via a long HTTP GET request to TCP port 5800, which triggers an overflow in VNCLog::ReallyPrint. | |||||
| CVE-2009-0388 | 2 Tightvnc, Ultravnc | 2 Tightvnc, Ultravnc | 2018-10-11 | 10.0 HIGH | N/A |
| Multiple integer signedness errors in (1) UltraVNC 1.0.2 and 1.0.5 and (2) TightVnc 1.3.9 allow remote VNC servers to cause a denial of service (heap corruption and application crash) or possibly execute arbitrary code via a large length value in a message, related to the (a) ClientConnection::CheckBufferSize and (b) ClientConnection::CheckFileZipBufferSize functions in ClientConnection.cpp. | |||||
| CVE-2006-2206 | 1 Ultravnc | 1 Ultravnc | 2017-07-19 | 10.0 HIGH | N/A |
| The MS-Logon authentication scheme in UltraVNC (aka Ultr@VNC) 1.0.1 uses weak encryption (XOR) for challenge/response, which allows remote attackers to gain privileges by sniffing and decrypting passwords. | |||||
| CVE-2016-5673 | 1 Ultravnc | 1 Repeater | 2016-11-28 | 5.0 MEDIUM | 7.5 HIGH |
| UltraVNC Repeater before 1300 does not restrict destination IP addresses or TCP ports, which allows remote attackers to obtain open-proxy functionality by using a :: substring in between the IP address and port number. | |||||
| CVE-2010-5248 | 1 Ultravnc | 1 Ultravnc | 2012-09-07 | 6.9 MEDIUM | N/A |
| Untrusted search path vulnerability in UltraVNC 1.0.8.2 allows local users to gain privileges via a Trojan horse vnclang.dll file in the current working directory, as demonstrated by a directory that contains a .vnc file. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2008-0610 | 1 Ultravnc | 1 Ultravnc | 2012-08-13 | 9.3 HIGH | N/A |
| Stack-based buffer overflow in the ClientConnection::NegotiateProtocolVersion function in vncviewer/ClientConnection.cpp in vncviewer for UltraVNC 1.0.2 and 1.0.4 before 01252008, when in LISTENING mode or when using the DSM plugin, allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a modified size value. | |||||
| CVE-2008-5001 | 1 Ultravnc | 1 Ultravnc | 2011-03-07 | 9.3 HIGH | N/A |
| Multiple stack-based buffer overflows in multiple functions in vncviewer/FileTransfer.cpp in vncviewer for UltraVNC 1.0.2 and 1.0.4 before 01252008, when in LISTENING mode or when using the DSM plugin, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified parameters, a different issue than CVE-2008-0610. | |||||
