CVE-2019-15691

Priority
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. 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.
