NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp-devel package and not the freerdp-devel package as distributed by AlmaLinux. See How to fix? for AlmaLinux:10 relevant fixed versions and status.

FreeRDP versions before 3.31.0 contain a heap buffer overflow vulnerability in nego_send_negotiation_request() that fails to validate the LB_LOAD_BALANCE_INFO field length before writing to a fixed 512-byte buffer. A malicious RDP server or man-in-the-middle can send a Server Redirection PDU with an oversized LB_LOAD_BALANCE_INFO value to overflow the buffer with attacker-controlled content, causing denial of service or heap corruption before authentication completes.
