An attacker could perform arbitrary code execution on a target computer with Git installed by creating a malicious Git tree (directory) named .git (a directory in Git repositories that stores all the data of the repository) in a different case (such as .GIT or .Git, needed because Git does not allow the all-lowercase version of .git to be ...
"foo" is not recognized as an internal or external command, operable program or batch file. Some early Unix shells produced the equally cryptic " foo: no such file or directory " again accurately describing what is wrong but confusing users.
Shellshock, also known as Bashdoor, [1] is a family of security bugs [2] in the Unix Bash shell, the first of which was disclosed on 24 September 2014.Shellshock could enable an attacker to cause Bash to execute arbitrary commands and gain unauthorized access [3] to many Internet-facing services, such as web servers, that use Bash to process requests.
Source Code Control System (SCCS) [open, shared] – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions; extracting an arbitrary version takes essentially the same time and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions
Bash can execute the vast majority of Bourne shell scripts without modification, with the exception of Bourne shell scripts stumbling into fringe syntax behavior interpreted differently in Bash or attempting to run a system command matching a newer Bash builtin, etc. Bash command syntax includes ideas drawn from the Korn Shell (ksh) and the C ...
The user will only see the blue screen if the system is not configured to automatically restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply rebooted (though a blue screen may be visible briefly). In Windows, bug checks are only supported by the Windows NT kernel.
This modified m4 file was not present in the git repository; it was only available from tar files released by the maintainer separate from git. [4] The script appears to perform the injection only when the system is being built on an x86-64 Linux system that uses glibc and GCC and is being built via dpkg or rpm. [4]
In Unix, the environment variables are normally initialized during system startup by the system init startup scripts, and hence inherited by all other processes in the system. Users can, and often do, augment them in the profile script for the command shell they are using.
