"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-014 advisory.

    A flaw was found in vim. A possible heap-based buffer overflow vulnerability allows an attacker to input a
    specially crafted file, leading to a crash or code execution. The highest threat from this vulnerability
    is system availability. (CVE-2021-4019)

    vim is vulnerable to Use After Free (CVE-2021-4069)

    A flaw was found in vim. A possible heap-based buffer overflow could allow an attacker to input a
    specially crafted file leading to a crash or code execution. (CVE-2021-4136)

    A flaw was found in vim. A possible heap-based buffer overflow could allow an attacker to input a
    specially crafted file leading to a crash or code execution. (CVE-2021-4166)

    A flaw was found in vim. A possible use after free vulnerability could allow an attacker to input a
    specially crafted file leading to a crash or code execution. (CVE-2021-4173)

    A flaw was found in vim. A possible use after free vulnerability could allow an attacker to input a
    specially crafted file leading to a crash or code execution. (CVE-2021-4187)

    It was found that vim was vulnerable to use-after-free flaw in win_linetabsize(). Sourcing a specially
    crafted file in vim could crash the vim process or possibly lead to other undefined behaviors.
    (CVE-2021-4192)

    It was found that vim was vulnerable to an out-of-bound read flaw in getvcol(). A specially crafted file
    could be used to, when opened in vim, disclose some of the process's internal memory. (CVE-2021-4193)

    vim is vulnerable to Out-of-bounds Read (CVE-2022-0128)

    It was found that vim was vulnerable to use-after-free flaw in the way it was treating allocated lines in
    user functions. A specially crafted file could crash the vim process or possibly lead to other undefined
    behaviors. (CVE-2022-0156)

    It was found that vim was vulnerable to a 1 byte heap based out of bounds read flaw in the
    `compile_get_env()` function. A file could use that flaw to disclose 1 byte of vim's internal memory.
    (CVE-2022-0158)
