CVE-2025-26601 (GCVE-0-2025-26601)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:55 – Updated: 2025-11-06 21:09
VLAI?
Summary
A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.
Severity ?
7.8 (High)
CWE
- CWE-416 - Use After Free

CVE-2025-26599 (GCVE-0-2025-26599)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:55 – Updated: 2025-11-06 21:09
VLAI?
Summary
An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later.
Severity ?
7.8 (High)
CWE
- CWE-824 - Access of Uninitialized Pointer
Assigner

CVE-2025-26598 (GCVE-0-2025-26598)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access.
Severity ?
7.8 (High)
CWE
- CWE-787 - Out-of-bounds Write

CVE-2025-26597 (GCVE-0-2025-26597)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.
Severity ?
7.8 (High)
CWE
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2025-26595 (GCVE-0-2025-26595)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
Severity ?
7.8 (High)
CWE
- CWE-121 - Stack-based Buffer Overflow

CVE-2024-0408 (GCVE-0-2024-0408)
Vulnerability from cvelistv5 – Published: 2024-01-18 15:40 – Updated: 2025-11-20 07:08
VLAI?
Summary
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.
Severity ?
5.5 (Medium)
CWE
- CWE-158 - Improper Neutralization of Null Byte or NUL Character

CVE-2020-26117 (GCVE-0-2020-26117)
Vulnerability from cvelistv5 – Published: 2020-09-27 03:30 – Updated: 2024-08-04 15:49
VLAI?
Summary
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.
Severity ?
No CVSS data available.

VLAI?
Summary
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-2019-15695 (GCVE-0-2019-15695)
Vulnerability from cvelistv5 – Published: 2019-12-26 15:24 – Updated: 2024-08-05 00:56
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2019-15691 (GCVE-0-2019-15691)
Vulnerability from cvelistv5 – Published: 2019-12-26 14:52 – Updated: 2024-08-05 00:56
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2011-1775 (GCVE-0-2011-1775)
Vulnerability from cvelistv5 – Published: 2011-05-26 18:00 – Updated: 2024-08-06 22:37
VLAI?
Summary
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.
Severity ?
No CVSS data available.
