Description

Tyler Bohan of Talos discovered that FreeRDP, a free implementation of the Remote Desktop Protocol (RDP), contained several vulnerabilities that allowed a malicious remote server or a man-in-the-middle to either cause a DoS by forcibly terminating the client, or execute arbitrary code on the client side.

For Debian 7

the Remote Desktop Protocol (RDP), contained several vulnerabilities
that allowed a malicious remote server or a man-in-the-middle to
either cause a DoS by forcibly terminating the client, or execute
arbitrary code on the client side.

For Debian 7 'Wheezy', these problems have been fixed in version
1.0.1-1.1+deb7u4.

We recommend that you upgrade your freerdp packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
