NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp-libs package and not the freerdp-libs package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

FreeRDP before 3.32.2 contains a heap buffer overflow in transport_default_read_pdu when handling partial Early User Authorization reads during PROTOCOL_HYBRID_EX CredSSP. A malicious RDP server can split the four-byte EUA result into short reads that advance the stream pointer beyond the 16 KiB allocation, causing an out-of-bounds write and client denial of service.
