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)

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