Summary

Moderate: freerdp and vinagre security, bug fix, and enhancement update

Details

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.

The vinagre packages provide the Vinagre remote desktop viewer for the GNOME desktop.

The following packages have been upgraded to a later upstream version: freerdp (2.1.1). (BZ#1834287)

Security Fix(es):

freerdp: Out of bound read in cliprdr_server_receive_capabilities (CVE-2020-11018)
freerdp: Out of bound read/write in usb redirection channel (CVE-2020-11039)
freerdp: out-of-bounds read in update_read_icon_info function (CVE-2020-11042)

freerdp: out-of-bounds read in irp functions (CVE-2020-11089)
freerdp: out-of-bounds read in gdi.c (CVE-2020-11522)
freerdp: out-of-bounds read in bitmap.c (CVE-2020-11525)
freerdp: Stream pointer out of bounds in update_recv_secondary_order could lead out of bounds read later (CVE-2020-11526)

CNVD-2020-31410

Vulnerability from cnvd - Published: 2020-06-03

Title

FreeRDP缓冲区溢出漏洞（CNVD-2020-31410）

Description

FreeRDP是FreeRDP团队的一款开源的远程桌面协议（RDP）的实现。 FreeRDP 2.1.1之前版本中的winpr/libwinpr/sspi/NTLM/ntlm_message.c文件的ntlm_read_ChallengeMessage存在缓冲区溢出漏洞。该漏洞源于网络系统或产品在内存上执行操作时，未正确验证数据边界，导致向关联的其他内存位置上执行了错误的读写操作。攻击者可利用该漏洞导致缓冲区溢出或堆溢出等。
