Several remote vulnerabilities have been discovered in rdesktop, a Remote Desktop Protocol client. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2008-1801 Remote exploitation of an integer underflow vulnerability allows attackers to execute arbitrary code with the privileges of the logged-in user.

  • CVE-2008-1802 Remote exploitation of a BSS overflow vulnerability allows attackers to execute arbitrary code with the privileges of the logged-in user.

  • CVE-2008-1803 Remote exploitation of an integer signedness vulnerability allows attackers to execute arbitrary code with the privileges of the logged-in user.
