Vulnerability Title
Out-of-bounds read in the camera device enumerator server (rdpecam) via unterminated DeviceName / VirtualChannelName
Source: CVE Program / CVE List V5
Vulnerability Description
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.

Vulnerability Description
FreeRDP是FreeRDP团队开源的一款开源的远程桌面协议(RDP)的实现。 FreeRDP 3.28.0之前版本存在缓冲区错误漏洞，该漏洞源于服务器在启用MS-RDPECAM摄像头设备枚举器通道时，扫描攻击者提供的DeviceName和VirtualChannelName字段以查找NUL终止符并超出边界解引用，允许恶意RDP客户端触发1到2字节的越界堆读取。
