gnuplot vulnerabilities

Tim Blazytko, Cornelius Aschermann, Sergej Schumilo and Nils Bars
discovered that Gnuplot did not properly validate string sizes in the
df_generate_ascii_array_entry function. An attacker could possibly use
this issue to cause a heap buffer overflow, resulting in a denial of
service attack or arbitrary code execution. (CVE-2018-19490)

Tim Blazytko, Cornelius Aschermann, Sergej Schumilo and Nils Bars
discovered that Gnuplot did not properly validate string sizes in the
PS_options function when the Gnuplot postscript terminal is used as a
backend. An attacker could possibly use this issue to cause a buffer
overflow, resulting in a denial of service attack or arbitrary code
execution. (CVE-2018-19491)
