CVE-2020-26117
In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception.
- Update to 1.10.1+dfsg-9
Published UpdatedCVE-2019-15695
TigerVNC version prior to 1.10.1 is vulnerable to stack buffer overflow, which could be triggered from CMsgReader::readSetCursor. This vulnerability occurs due to insufficient sanitization of PixelFormat. Since remote attacker can choose offset from start of the buffer to start writing his values, exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
- Update to 1.10.1+dfsg-1
Published UpdatedCVE-2019-15694
TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow, which could be triggered from DecodeManager::decodeRect. Vulnerability occurs due to the signdness error in processing MemOutStream. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
- Update to 1.10.1+dfsg-1
Published UpdatedCVE-2019-15693
TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow, which occurs in TightDecoder::FilterGradient. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
- Update to 1.10.1+dfsg-1
Published UpdatedCVE-2019-15692
TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow. Vulnerability could be triggered from CopyRectDecoder due to incorrect value checks. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
- Update to 1.10.1+dfsg-1
Published UpdatedCVE-2019-15691
TigerVNC version prior to 1.10.1 is vulnerable to stack use-after-return, which occurs due to incorrect usage of stack memory in ZRLEDecoder. If decoding routine would throw an exception, ZRLEDecoder may try to access stack variable, which has been already freed during the process of stack unwinding. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.

Published UpdatedCVE-2017-7396
In TigerVNC 1.7.1 (CConnection.cxx CConnection::CConnection), an unauthenticated client can cause a small memory leak in the server.
- Update to 1.7.0+dfsg-7
Published UpdatedCVE-2017-7395
In TigerVNC 1.7.1 (SMsgReader.cxx SMsgReader::readClientCutText), by causing an integer overflow, an authenticated client can crash the server.
- Update to 1.7.0+dfsg-7
Published UpdatedCVE-2017-7394
In TigerVNC 1.7.1 (SSecurityPlain.cxx SSecurityPlain::processMsg), unauthenticated users can crash the server by sending long usernames.
- Update to 1.7.0+dfsg-7
Published UpdatedCVE-2017-7393
In TigerVNC 1.7.1 (VNCSConnectionST.cxx VNCSConnectionST::fence), an authenticated client can cause a double free, leading to denial of service or potentially code execution.
- Update to 1.7.0+dfsg-7
Published UpdatedCVE-2017-7392
In TigerVNC 1.7.1 (SSecurityVeNCrypt.cxx SSecurityVeNCrypt::SSecurityVeNCrypt), an unauthenticated client can cause a small memory leak in the server.
- Update to 1.7.0+dfsg-7
Published UpdatedCVE-2017-5581
Buffer overflow in the ModifiablePixelBuffer::fillRect function in TigerVNC before 1.7.1 allows remote servers to execute arbitrary code via an RRE message with subrectangle outside framebuffer boundaries.
- Update to 1.7.0+dfsg-3
Published UpdatedCVE-2016-10207
The Xvnc server in TigerVNC allows remote attackers to cause a denial of service (invalid memory access and crash) by terminating a TLS handshake early.
- Update to 1.7.0-1
Published UpdatedCVE-2014-8241
XRegion in TigerVNC allows remote VNC servers to cause a denial of service (NULL pointer dereference) by leveraging failure to check a malloc return value, a similar issue to CVE-2014-6052.
- Update to 1.7.0-2
Published UpdatedCVE-2014-8240
Integer overflow in TigerVNC allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to screen size handling, which triggers a heap-based buffer overflow, a similar issue to CVE-2014-6051.
- Update to 1.7.0-1
