High impact if exploited, but EPSS currently rates exploitation as unlikely (2.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A heap-based overflow vulnerability exists in the PowerPoint document conversion function of Rainbow PDF Office Server Document Converter V7.0 Pro R1 (7,0,2018,1113). While parsing Document Summary Property Set stream, the getSummaryInformation function is incorrectly checking the correlation between size and the number of properties in PropertySet packets, causing an out-of-bounds write that leads to heap corruption and consequent code execution.
