rdesktop iso_recv_msg function code execution
| rdesktop-isorecvmsg-code-execution (42272) |  High Risk |
Description:
rdesktop is vulnerable to a heap-based buffer overflow, caused by an integer underflow in the iso_recv_msg function. By persuading a victim to connect to a malicious RDP server, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the victim or cause the application to crash.
