CVE-2018-19491
This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the PS_options function.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.77%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
