![]() With a 64-bit Visual Studio on Windows, you can open, edit, run, and debug even the biggest and most complex solutions without running out of memory. Visual Studio 2022 will be a 64-bit application, no longer limited to ~4gb of memory in the main devenv.exe process. We’re making it easier to collaborate with better GitHub integration making it seamless to go from idea to code to the cloud. It’s become apparent over the last year that organizations need their development teams to collaborate securely, deliver solutions more quickly, and continuously improve their end-user satisfaction and value. The user experience will feel cleaner, intelligent, and action oriented.ĭevelopment teams have become more geographically dispersed than ever. For the first time ever, Visual Studio will be 64-bit. Sudo - sh -c 'rm -rf /private/tmp/ios-docs-download.Visual Studio 2022 by Microsoft will be faster, more approachable, and more lightweight, designed for both learners and those building industrial scale solutions. Pkgutil -expand $dir_path/iOSDocset.pkg $tmp_unpackĮcho "*** press CRL+C when the download starts ***" If hdiutil attach $target_path -mountroot $mount_path -nobrowse > $TMPDIR/output thenĭir_path=`awk '$2 ~ /Apple_HFS/ ' $TMPDIR/output` # See if we have apple doc and if not get it The files located in the DMG file will appear in a folder under this mount root. Using symbolic links the attacker can control the mount root where the DMG file will be mounted, for example the DMG file can be mounted under /etc. In this case the attacker can return the original DMG file when the MD5 check is done, and return a different one when it is mounted with hdiutil. This check can be circumvented using a named pipe. Since the attacker can control the work directory it is (partially) possible to control where the files are extracted.īefore the DMG is mounted and the files are extracted, the script first checks the MD5 digest of the DMG file against a hard coded value. If the folder ~/Library/Developer/Shared/Documentation/DocSets does not exist, the script will download a DMG file from internet, mount it and extract files from a PKG files that is located in the DMG file. NET Assemblies (DLLs) that are later used by the mdoc application. This folder is used for storing a number of. The script performs very little error checking, if a certain step fails (eg, the target directory exists) the script usually continues executing the next command. It is even possible to pre-create all possible folder names (as symbolic links). Since these identifiers are sequential it is not very hard for an attacker to predict what the folder name will be. This directory is created under /tmp, the only 'random' part is the process identifier of the script. ![]() Looking at the script, the first thing that probably stands out is the fact the script uses an insecure work directory. Yet there are still flaws in the current implementation that (potentially) allow a local attacker to gain elevated privileges. Some attacks are prevented due to the housekeeping done by apple-doc-wizard/sudo. Letting local users run scripts with root privileges is generally advised against. When it start some housekeeping is done like cleaning the PATH environment variable after which the script apple-doc-wizard.sh is run (through sudo). Some steps in this update process require root privileges and consequently the application is installed as setuid root. Xamarin Studio ships with the apple-doc-wizard application that is used to update the API documentation for the Xamarin.iOS SDK. ![]() Xamarin Studio supports developments in C# and F# (by default). Xamarin Studio is an Integrated Development Environment (IDE) used to create iOS, Mac and Android applications. However, as of 2019 the documentation is no longer available (support ID 4037359). Microsoft released a new version of Xamarin.iOS that addresses this issue. This issue was successfully verified on Xamarin Studio for Mac version 6.2.1 (build 3) and version 6.3 (build 863). CVE-2017-8665 | Xamarin.iOS Elevation Of Privilege Vulnerability. ![]() ![]() This update mechanism contains several flaws that could be leveraged by a local attacker to gain elevated (root) privileges. The API documentation update mechanism of Xamarin Studio for Mac is installed as setuid root. ![]()
