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.");
