Apple has released a new version of its Xcode development tool in order to patch two critical vulnerabilities in the Git source code management client. The Git vulnerabilities have been known since mid-March and can be exploited when cloning a repository with a specially crafted file structure. This allows attackers to execute malicious code on systems where such cloning operations were initiated. Xcode is an integrated development environment (IDE) used by a large number of developers to write applications for OS X and iOS. Some systems administrators criticized Apple last month for dragging its feet on importing the upstream patches for such serious flaws.”]
