CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-11-21 | N/A | 7.6 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 | 2024-11-21 | 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-2020-26117 | 3 Debian, Opensuse, Tigervnc | 3 Debian Linux, Leap, Tigervnc | 2024-11-21 | 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-2019-15695 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2024-11-21 | 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-2019-15694 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2024-11-21 | 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-2019-15693 | 1 Tigervnc | 1 Tigervnc | 2024-11-21 | 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-2019-15692 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2024-11-21 | 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 | 2 Opensuse, Tigervnc | 2 Leap, Tigervnc | 2024-11-21 | 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-2014-0011 | 1 Tigervnc | 1 Tigervnc | 2024-11-21 | 7.5 HIGH | 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. |
