Debian Security Advisory

DLA-1597-1 gnuplot -- LTS security update

Date Reported:
26 Nov 2018
Affected Packages:
gnuplot
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2018-19490, CVE-2018-19491, CVE-2018-19492.
More information:

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.
