The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
vim: buffer overflow (CVE-2020-20703)
vim: use-after-free in skipwhite() in charset.c (CVE-2022-2345)
libvterm through 0+bzr726, as used in Vim and other products, mishandles certain out-of-memory conditions, leading to a denial of service (application crash), related to screen.c, state.c, and vterm.c.
(CVE-2018-20786)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
