Description

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.

Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
