Package : gtk-vnc
Version : 0.5.0-3.1+deb7u1
CVE ID : CVE-2017-5884 CVE-2017-5885
Debian Bug : 854450

Josef Gajdusek discovered two vulnerabilities in gtk-vnc, a VNC viewer
widget for GTK:

CVE-2017-5884

Fix bounds checking for RRE, hextile & copyrec encodings. This bug
allowed a remote server to cause a denial of service by buffer
overflow via a carefully crafted message containing subrectangles
outside the drawing area.

CVE-2017-5885

Correctly validate color map range indexes. This bug allowed a
remote server to cause a denial of service by buffer overflow via
a carefully crafted message with out-of-range colour values.

For Debian 7 "Wheezy", these problems have been fixed in version
0.5.0-3.1+deb7u1.

We recommend that you upgrade your gtk-vnc packages.

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
found at: https://wiki.debian.org/LTS
