Application and Change Control (ACC) 8.x
Problem
Applications running in a Windows environment with ACC installed experience increased start times when the Cause
The As part of its set of Memory Protection techniques, ACC offers Virtual Area Space Randomization (VASR). This feature forces the relocation of dynamic-link libraries ( When the operating system runs a program, the executable is held in memory. The executable is held in a specific way that's consistent between different processes. The operating system calls the main method of the code as a function. It then starts the flow for the rest of the program. A buffer overflow exploit requires an attacker to know where each part of the program is located in memory. Figuring out the location in memory is difficult. It's done by trial and error. When the location in memory is identified, the attacker must craft a payload and find a suitable place to inject it. If the attacker doesn't know the location of the target code, it's almost impossible to exploit it. VASR works by randomizing the memory location where the program loads a SolutionACC fills the gap for Windows XP, 2003 and Vista if applications aren't built with ASLR. For Windows 7 and later, all system libraries are built with ASLR. Protection is always on and it can't be configured. Technical Support recommends disabling VASR protection for systems running ACC in a Windows 7 or later environment. To avoid conflicts, use the native protection offered by the operating system.
