Description
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.
Statement
Gnuplot allows for trivial execution of arbitrary commands from within gnuplot files by design. As such, gnuplot files should be considered as inherently dangerous and users should only execute files from trusted sources.
