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-2022-1557 advisory.

- Buffer Overflow vulnerability in VIM v.8.1.2135 allows a remote attacker to execute arbitrary code via the operand parameter. (CVE-2020-20703)

- vim is vulnerable to Heap-based Buffer Overflow (CVE-2021-3903, CVE-2021-3927, CVE-2021-3968, CVE-2021-3973, CVE-2021-3984, CVE-2021-4019, CVE-2021-4136)

- vim is vulnerable to Out-of-bounds Read (CVE-2021-4166, CVE-2021-4193)
