Name of the Vulnerable Software and Affected Versions rdesktop versions up to and including v1.8.3

Description The issue is related to the implementation of the cssp read tsrequest function in the RDP client, which is associated with an out-of-bounds memory read. This can be exploited by a remote attacker to cause a denial of service, resulting in a crash.

Recommendations For rdesktop versions up to and including v1.8.3, consider disabling the cssp read tsrequest function as a temporary workaround until a patch is available.
