Amazon Linux 2 : vim (ALAS-2024-2452)

high Nessus Plugin ID 190020

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2452 advisory.

- Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue. (CVE-2023-48706)

- Vim before 9.0.2142 has a stack-based buffer overflow because did_set_langmap in map.c calls sprintf to write to the error buffer that is passed down to the option callback functions. (CVE-2024-22667)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update vim' to update your system.
