CVE-2018-8788
FreeRDP prior to version 2.0.0-rc4 contains an Out-Of-Bounds Write of up to 4 bytes in function nsc_rle_decode() that results in a memory corruption and possibly even a remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
