CVE-2021-3928 [MEDIUM] Vim vulnerabilities
Title: Vim vulnerabilities
Summary: Several security issues were fixed in Vim.
It was discovered that Vim incorrectly handled permissions on the .swp
file. A local attacker could possibly use this issue to obtain sensitive
information. This issue only affected Ubuntu 14.04 ESM. (CVE-2017-17087)
It was discovered that Vim incorrectly handled restricted mode. A local
attacker could possibly use this issue to bypass restricted mode and
execute arbitrary commands. Note: This update only makes executing shell
commands more difficult. Restricted mode should not be considered a
complete security measure. This issue only affected Ubuntu 14.04 ESM.

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.

vim: heap-based buffer overflow in gchar_cursor() in misc1.c
vim is vulnerable to Heap-based Buffer Overflow
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. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement: This vulnerability can only be exloited if the victim opens a specifically crafter file that will cause the heap to overflow. Considering the mitigations like ASLR available in the Linux kernel and the user interaction required, RH ProdSec has set the Impact of this vulnerability to "Low"
Mitigation: Do not run untrusted vim scripts with -s {scriptin} as it is never safe to do so.
