Several vulnerabilities were discovered in rdesktop, a Remote Desktop Protocol client. An integer underflow vulnerability allowed attackers to cause a denial of service and possibly execute arbitrary code with the privileges of the logged-in user . A buffer overflow vulnerability allowed attackers to execute arbitrary code with the privileges of the logged-in user . An integer signedness vulnerability allowed attackers to execute arbitrary code with the privileges of the logged-in user . In order for these vulnerabilities to be exploited, an attacker must persuade a targeted user to connect to a malicious RDP server. The updated packages have been patched to correct these issues.
