NVD Description
Note: Versions mentioned in the description apply only to the upstream gnuplot package and not the gnuplot package as distributed by Ubuntu.
An issue was discovered in datafile.c in Gnuplot 5.2.5. This issue allows an attacker to conduct a heap-based buffer overflow with an arbitrary amount of data in df_generate_ascii_array_entry. To exploit this vulnerability, an attacker must pass an overlong string as the right bound of the range argument that is passed to the plot function.
