The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4631-1 advisory.

Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0742. (CVE-2022-3491)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0765. (CVE-2022-3520)
Use After Free in GitHub repository vim/vim prior to 9.0.0789. (CVE-2022-3591)
A vulnerability was found in vim and classified as problematic. Affected by this issue is the function qf_update_buffer of the file quickfix.c of the component autocmd Handler. The manipulation leads to use after free. The attack may be launched remotely. Upgrading to version 9.0.0805 is able to address this issue. The name of the patch is d0fab10ed2a86698937e3c3fed2f10bd9bb5e731. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-212324. (CVE-2022-3705)
Heap based buffer overflow in vim/vim 9.0.0946 and below by allowing an attacker to CTRL-W gf in the expression used in the RHS of the substitute command. (CVE-2022-4141)
Use After Free in GitHub repository vim/vim prior to 9.0.0882. (CVE-2022-4292)
Floating Point Comparison with Incorrect Operator in GitHub repository vim/vim prior to 9.0.0804.
(CVE-2022-4293)

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