CVE-2022-0729 [HIGH] Vim vulnerabilities
Title: Vim vulnerabilities
Summary: Several security issues were fixed in Vim.
It was discovered that Vim was incorrectly processing Vim buffers. An
attacker could possibly use this issue to perform illegal memory access and
expose sensitive information. This issue only affected Ubuntu 20.04 LTS.
(CVE-2021-4166)
It was discovered that Vim was using freed memory when dealing with regular
expressions inside a visual selection. If a user were tricked into opening a
specially crafted file, an attacker could crash the application, leading to a
denial of service, or possibly achieve code execution with user privileges.
This issue only affected Ubuntu 14.04 ESM, Ubuntu 18.04 LTS and Ubuntu
20.04 LTS. (CVE-2021-4192)
It was discovered that Vim was incorrectly handling virtual column position

vim: out-of-bounds read in do_arg_all() in src/arglist.c
vim is vulnerable to Out-of-bounds Read
A flaw was found in vim. A possible heap-based buffer overflow could allow an attacker to input a specially crafted file leading to a crash or code execution.
Statement: Red Hat Product Security has rated this issue as having a Low security impact, because the "victim" has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it.

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.
