New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the freerdp packages.

For the oldstable distribution (jessie), these problems have been fixed in version 1.1.0~git20140921.1.440916e+dfsg1-4+deb8u1.

For the stable distribution (stretch), these problems have been fixed in version 1.1.0~git20140921.1.440916e+dfsg1-13+deb9u1.
