- Summary
- FreeRDP 2.0.0 before 3.32.0 Heap Out-of-Bounds Write via NTLM MIC Offset
- Details
-
FreeRDP versions from 2.0.0 before 3.32.0 contain a heap out-of-bounds write in the server hash-callback NTLM path that fails to validate the MIC offset. Unauthenticated attackers can send a crafted AUTHENTICATE_MESSAGE with a backward session-key offset and MIC offset to write 16 zero bytes beyond the allocation.
