| CVE-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-01-11 | N/A | 7.8 HIGH |
| A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. | |||||
| CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-01-11 | N/A | 7.5 HIGH |
| A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information. | |||||
| CVE-2020-26117 | 3 Debian, Opensuse, Tigervnc | 3 Debian Linux, Leap, Tigervnc | 2020-11-06 | 5.8 MEDIUM | 8.1 HIGH |
| 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. | |||||
| CVE-2019-15694 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2020-10-16 | 6.5 MEDIUM | 7.2 HIGH |
| 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. | |||||
| CVE-2019-15695 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2020-10-16 | 6.5 MEDIUM | 7.2 HIGH |
| 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. | |||||
| CVE-2019-15692 | 1 Tigervnc | 1 Tigervnc | 2020-01-21 | 6.5 MEDIUM | 7.2 HIGH |
| 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. | |||||
| CVE-2019-15691 | 1 Tigervnc | 1 Tigervnc | 2020-01-21 | 6.5 MEDIUM | 7.2 HIGH |
| 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. | |||||
| CVE-2019-15693 | 1 Tigervnc | 1 Tigervnc | 2020-01-21 | 6.5 MEDIUM | 7.2 HIGH |
| 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. | |||||
| CVE-2017-7396 | 1 Tigervnc | 1 Tigervnc | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| In TigerVNC 1.7.1 (CConnection.cxx CConnection::CConnection), an unauthenticated client can cause a small memory leak in the server. | |||||
| CVE-2017-7392 | 1 Tigervnc | 1 Tigervnc | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| In TigerVNC 1.7.1 (SSecurityVeNCrypt.cxx SSecurityVeNCrypt::SSecurityVeNCrypt), an unauthenticated client can cause a small memory leak in the server. | |||||
| CVE-2016-10207 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2018-02-01 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2017-7394 | 1 Tigervnc | 1 Tigervnc | 2018-01-13 | 5.0 MEDIUM | 7.5 HIGH |
| In TigerVNC 1.7.1 (SSecurityPlain.cxx SSecurityPlain::processMsg), unauthenticated users can crash the server by sending long usernames. | |||||
| CVE-2017-7393 | 1 Tigervnc | 1 Tigervnc | 2018-01-13 | 6.5 MEDIUM | 8.8 HIGH |
| 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. | |||||
