An issue in datafile.c allows an attacker to conduct a heap-based buffer overflow with an arbitrary amount of data in `df generate ascii array entry()`. This can be exploited by passing an overlong string as the right bound of the range argument to the `plot()` function.

An issue in Gnuplot allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the `PS options` function. This flaw is caused by a missing size check of an argument passed to the `set font` function. The issue occurs when the Gnuplot postscript terminal is used as a backend.

A buffer overflow issue exists due to a missing size check of an argument passed to the `set font` function, specifically in the `cairotrm options` function when the Gnuplot pngcairo terminal is used as a backend. This allows an attacker to conduct a buffer overflow with an arbitrary amount of data.
