Name of the Vulnerable Software and Affected Versions
Gnuplot version 5.2.5
Description
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.Recommendations
For Gnuplot version 5.2.5, consider disabling the
cairotrm options function or restricting the use of the pngcairo terminal as a backend until a patch is available. Avoid using the set font function with untrusted input to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
