USN-4541-1

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)
