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...

The vulnerability of the ZRLEDecoder software, which is part of VNC TigerVNC, allows a hacker to gain access to confidential data, compromise its integrity, and cause service interruptions.

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...

The vulnerability of the zrle_compress_data function in the software for emulating hardware on various QEMU platforms arises from improper memory release before deleting the last reference. This allows a malicious actor to trigger a service failure.

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...
