Summary
FreeRDP is a free implementation of the Remote Desktop Protocol.
Prior to 3.28.0, FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied DeviceName and VirtualChannelName fields for a NUL terminator in channels/rdpecam/server/camera_device_enumerator_main.c and then dereference once past the scan bound, allowing a malicious RDP client to trigger a 1- to 2-byte out-of-bounds heap read.
This issue is fixed in version 3.28.0. A malicious RDP client can exploit this by manipulating the DeviceName and VirtualChannelName fields, which can lead to information disclosure and denial of service.
