Debian DLA-1597-1 : gnuplot security update

Medium Nessus Plugin ID 119266

Synopsis

The remote Debian host is missing a security update.

Description

gnuplot, a command-line driven interactive plotting program, has been examined with fuzzing by Tim Blazytko, Cornelius Aschermann, Sergej Schumilo and Nils Bars. They found various overflow cases which might lead to the execution of arbitrary code.

Due to special toolchain hardening in Debian, CVE-2018-19492 is not security relevant, but it is a bug and the patch was applied for the sake of completeness. Probably some downstream project does not have the same toolchain settings.

For Debian 8 'Jessie', these problems have been fixed in version 4.6.6-2+deb8u1.

We recommend that you upgrade your gnuplot packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
