Integer underflow in the isorecvmsg function (iso.c) in rdesktop 1.5.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Remote Desktop Protocol (RDP) request with a small length field.

Buffer overflow in the processredirectpdu (rdp.c) function in rdesktop 1.5.0 allows remote attackers to execute arbitrary code via a Remote Desktop Protocol (RDP) redirect request with modified length fields.

Integer signedness error in the xrealloc function (rdesktop.c) in RDesktop 1.5.0 allows remote attackers to execute arbitrary code via unknown parameters that trigger a heap-based overflow. NOTE: the role of the channelprocess function was not specified by the original researcher.

Directory traversal vulnerability in the diskcreate function in disk.c in rdesktop before 1.7.0, when disk redirection is enabled, allows remote RDP servers to read or overwrite arbitrary files via a .. (dot dot) in a pathname.
