The DOS/Windows spawn functions are inspired by Unix functions fork and exec; however, as these operating systems do not support fork, [2] the spawn function was supplied as a replacement for the fork-exec combination. However, the spawn function, although it deals adequately with the most common use cases, lacks the full power of fork-exec ...
Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
Moreover, many software bugs which cause crashes are also exploitable for arbitrary code execution and other types of privilege escalation. [7] [8] For example, a stack buffer overflow can overwrite the return address of a subroutine with an invalid value, which will cause, e.g., a segmentation fault, when the subroutine returns. However, if an ...
The Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Action Center on Windows 7 and Server 2008 R2.. A new app, Problem Steps Recorder (PSR.exe), is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis ...
The LIB file (import library) is used to link against a DLL at compile-time; it is not necessary for run-time linking. Unless the DLL is a Component Object Model (COM) server, the DLL file must be placed in one of the directories listed in the PATH environment variable, in the default system directory, or in the same directory as the program ...
CompactOS is an improved variant of WIMBoot from Windows 8.1, where system files could be stored in a compressed WIM image on a hidden disk partition, [22] and the WOF filter driver would decompress file contents from that WIM file; using alternate data streams instead of read-only WIM images allows CompactOS to recompress system files when ...
In older versions of Windows, programs which linked against MSVCRT.DLL were expected to install a compatible copy in the System32 folder, but this contributed to DLL Hell because many installers failed to check the library version against the installed version before replacing it.
BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...
