Package : x11vnc
CVE ID : CVE-2020-29074
Debian Bug : 975875

Guenal Davalan reported a flaw in x11vnc, a VNC server to allow remote
access to an existing X session. x11vnc creates shared memory segments
with 0777 mode. A local attacker can take advantage of this flaw for
information disclosure, denial of service or interfering with the VNC
session of another user on the host.

For the stable distribution (buster), this problem has been fixed in
version 0.9.13-6+deb10u1.

We recommend that you upgrade your x11vnc packages.

For the detailed security status of x11vnc please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/x11vnc
