critical Nessus Plugin ID 153468

Language:

Synopsis

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

Description

The remote SUSE Linux SLED12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3125-1 advisory.

- 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-2017-5884)

- 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. (CVE-2017-5885)

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 packages.
