Microsoft Windows winhlp32.exe buffer overflow
|ms-win-winhlp32-bo (56560)||High Risk|
Microsoft Windows is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by winhlp32.exe. By persuading a victim to open a specially-crafted .HLP file containing an overly long string in the fourth argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
