Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1893 advisory.

 Vim is an improved version of the good old UNIX editor Vi. Heap-use-after-free in memory allocated in the function `ga_grow_inner` in in the file `src/alloc.c` at line 748, which is freed in the file `src/ex_docmd.c` in the function `do_cmdline` at line 1010 and then used again in `src/cmdhist.c` at line 759. When using the `:history` command, it's possible that the provided argument overflows the accepted value. Causing an Integer Overflow and potentially later an use-after-free. This vulnerability has been patched in version 9.0.2068. (CVE-2023-46246)

 Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1969. (CVE-2023-5344)

 NULL Pointer Dereference in GitHub repository vim/vim prior to 20d161ace307e28690229b68584f2d84556f8960.
 (CVE-2023-5441)

 Use After Free in GitHub repository vim/vim prior to v9.0.2010. (CVE-2023-5535)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
