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

Description The issue is related to a Heap-Based Buffer Overflow in the process plane() function, which can result in memory corruption and potentially allow for remote code execution. The vulnerability in the process plane function implementation of the RDP client rdesktop is associated with a buffer overflow, and its exploitation may allow a remote attacker to execute arbitrary code.
