Name of the Vulnerable Software and Affected Versions Gnuplot version 5.2.5

Description 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.

Recommendations For Gnuplot version 5.2.5, as a temporary workaround, consider restricting the input to the plot() function to prevent overlong strings from being passed as the right bound of the range argument. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
