MiracleLinux 7 : gtk-vnc-0.7.0-2.el7 (AXSA:2017-1910:01)

critical Nessus Plugin ID 289861

Synopsis

The remote MiracleLinux host is missing one or more security updates.

Description

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-1910:01 advisory.

gtk-vnc is a VNC viewer widget for GTK2. It is built using coroutines allowing it to be completely asynchronous while remaining single threaded.
CVE-2017-5884 gtk-vnc before 0.7.0 does not properly check boundaries of subrectangle-containing tiles, which allows remote servers to execute arbitrary code via the src x, y coordinates in a crafted (1) rre, (2) hextile, or (3) copyrect tile.
CVE-2017-5885 Multiple integer overflows in the (1) vnc_connection_server_message and (2) vnc_color_map_set functions in gtk-vnc before 0.7.0 allow remote servers to cause a denial of service (crash) or possibly execute arbitrary code via vectors involving SetColorMapEntries, which triggers a buffer overflow.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected gtk-vnc2 and / or gvnc packages.
