FreeRDP: FreeRDP: Remote code execution or denial of service via heap-based buffer overflow

A heap-based buffer overflow in FreeRDP's cryptorsacommon allows an unauthenticated remote attacker to trigger a denial of service or potential remote code execution. By sending a crafted ciphertext during RDP Standard Security key establishment, the attacker can force a data write before the siz...

CVE-2026-64620 FreeRDP before 3.28.0 Heap Buffer Overflow via crypto_rsa_common

FreeRDP before 3.28.0 affected outlength, so out-of-bounds bytes are written before the bounds check. On the server side, when a client selects RDP Standard Security, the encrypted client random is decrypted into a fixed 32-byte buffer. Because the server publishes its RSA public key, an...
