CVE-2026-107611
GlavSoft TightVNC Viewer for Windows before version 2.8.88 is vulnerable to an out-of-bounds read in its ZRLE decoder . The issue occurs because the readPaletteRleTile() and readPackedPaletteTile() functions fail to validate attacker-supplied indices against the declared palette size. A malicious...

Linux Distros Unpatched Vulnerability : CVE-2019-15691
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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 routin...
SUSE CVE-2014-0011
Multiple heap-based buffer overflows in the ZRLEDECODE 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...
SUSE CVE-2019-20382
QEMU 4.1.0 has a memory leak in zrlecompressdata in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd...
ZRLEDecoder VNC TigerVNC Confidential Data Access DoS
The vulnerability of the ZRLEDecoder software, developed for VNC and TigerVNC protocols, relates to operations involving resources after their expiration. Exploiting this vulnerability can allow unauthorized individuals to gain access to confidential data, compromise its integrity, and cause...
QEMU Heap Buffer Overflow DoS
The vulnerability of the zrlecompressdata function in the software for emulating hardware on various QEMU platforms is related to improper memory release before deleting the last pointer. Exploiting this vulnerability can allow an attacker to gain access to confidential data, compromise its...
Important: qemu
Issue Overview: A memory leakage flaw was found in the way the VNC display driver of QEMU handled the connection disconnect when ZRLE and Tight encoding are enabled. Two VncState objects are created, and one allocates memory for the Zlib's data object. This allocated memory is not freed upon...
