Original Bulletin: 
   https://lists.debian.org/debian-lts-announce/2018/11/msg00031.html

Comment: This advisory references vulnerabilities in products which run on 
         platforms other than Debian. It is recommended that administrators 
         running gnuplot5 check for an updated version of the software for 
         their operating system.

Package        : gnuplot5
Version        : 5.0.0~rc+dfsg2-1+deb8u1
CVE ID         : CVE-2018-19490 CVE-2018-19491 CVE-2018-19492


gnuplot5, 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
5.0.0~rc+dfsg2-1+deb8u1.

We recommend that you upgrade your gnuplot5 packages.
