Title: Vim vulnerabilities
Summary: Several security issues were fixed in Vim.
Brian Carpenter discovered that vim incorrectly handled memory
when opening certain files. If a user was tricked into opening
a specially crafted file, a remote attacker could crash the
application, leading to a denial of service, or possibly execute
arbitrary code with user privileges. This issue only affected
Ubuntu 20.04 LTS and Ubuntu 21.04. (CVE-2021-3770)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
