These are all security issues fixed in the gnuplot-5.4.2-1.3 package on the GA media of openSUSE Tumbleweed.

Tim Blazytko, Cornelius Aschermann, Sergej Schumilo, and Nils Bars discovered that Gnuplot had several memory-related issues. An attacker could possibly use these issues to cause Gnuplot to experience a buffer overflow, resulting in a denial of service or arbitrary code execution. These issues only affected Ubuntu 14.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-19490, CVE-2018-19491, CVE-2018-19492)

It was discovered that Gnuplot could write out-of-bounds due to the use of strncpy(). An attacker could possibly use this issue to enable the execution of arbitrary code. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-25412)

It was discovered that Gnuplot incorrectly freed memory when executing print_set_output(). An attacker could possibly use this issue to enable the execution of arbitrary code. (CVE-2020-25559)

It was discovered that Gnuplot's plotrequest() function contained a buffer overflow. An attacker could possibly use this issue to cause Gnuplot to crash, resulting in a denial of service or arbitrary code execution. (CVE-2020-25969)

It was discovered that Gnuplot's boundary3d() function could be made to divide by zero. An attacker could possibly use this issue to cause Gnuplot to crash, resulting in a denial of service. (CVE-2021-44917)
