Multiple security issues were found in the rdesktop RDP client, which could result in denial of service, information disclosure and the execution of arbitrary code.
For Debian 8 ‘Jessie’, these problems have been fixed in version 1.8.4-0+deb8u1.
We recommend that you upgrade your rdesktop packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
