| CVE-2024-0409 | 4 Fedoraproject, Redhat, Tigervnc and 1 more | 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more | 2024-05-29 | 7.8 High |
| A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. | ||||
| CVE-2024-0408 | 4 Fedoraproject, Redhat, Tigervnc and 1 more | 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more | 2024-05-29 | 5.5 Medium |
| A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL. | ||||
| CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-05-29 | 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-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-05-29 | 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-2011-1775 | 1 Tigervnc | 1 Tigervnc | 2023-02-13 | N/A |
| The CSecurityTLS::processMsg function in common/rfb/CSecurityTLS.cxx in the vncviewer component in TigerVNC 1.1beta1 does not properly verify the server's X.509 certificate, which allows man-in-the-middle attackers to spoof a TLS VNC server via an arbitrary certificate. | ||||
| CVE-2019-15693 | 1 Tigervnc | 1 Tigervnc | 2023-01-20 | 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-2019-15692 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2022-12-22 | 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-2020-26117 | 3 Debian, Opensuse, Tigervnc | 3 Debian Linux, Leap, Tigervnc | 2022-11-16 | 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-2019-15691 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2022-11-09 | 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-2019-15695 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2020-10-16 | 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-2019-15694 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2020-10-16 | 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-2014-0011 | 1 Tigervnc | 1 Tigervnc | 2020-01-14 | 9.8 Critical |
| Multiple heap-based buffer overflows in the ZRLE_DECODE function in common/rfb/zrleDecode.h in TigerVNC before 1.3.1, when NDEBUG is enabled, allow remote VNC servers to cause a denial of service (vncviewer crash) and possibly execute arbitrary code via vectors related to screen image rendering. | ||||
| CVE-2017-7396 | 1 Tigervnc | 1 Tigervnc | 2019-10-03 | N/A |
| 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 | N/A |
| 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 | N/A |
| 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-2017-7395 | 1 Tigervnc | 1 Tigervnc | 2018-01-13 | N/A |
| In TigerVNC 1.7.1 (SMsgReader.cxx SMsgReader::readClientCutText), by causing an integer overflow, an authenticated client can crash the server. | ||||
| CVE-2017-7394 | 1 Tigervnc | 1 Tigervnc | 2018-01-13 | N/A |
| 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 | N/A |
| 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. | ||||
| CVE-2017-5581 | 1 Tigervnc | 1 Tigervnc | 2018-01-05 | N/A |
| 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. | ||||
| CVE-2014-8240 | 1 Tigervnc | 1 Tigervnc | 2017-09-08 | N/A |
| 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. | ||||
