Description
A flaw was found in Vim, an open-source command-line text editor. Specifically, an operating system (OS) command injection vulnerability exists in the netrw standard plugin. A remote attacker could exploit this by tricking a user into opening a specially crafted URL, such as one using the scp:// protocol handler. Successful exploitation allows the attacker to execute arbitrary shell commands with the same privileges as the Vim process, leading to potential system compromise.
Statement
The risk posed by this vulnerability is limited on Red Hat products due to user and system isolation features which are enabled by default. The impacts of this flaw will be limited by the active user's permissions and access control limits. Host systems are not at risk when following Red Hat guidelines and the root user account is not actively executing Vim.
