Description
An issue was discovered in post.trm in Gnuplot 5.2.5. This issue 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. This issue occurs when the Gnuplot postscript terminal is used as a backend.
