following vulnerabilities :

  - Out-of-bounds Read in vim/vim prior to 8.2. (CVE-2022-0319)

  - Heap-based Buffer Overflow in GitHub repository vim/vim prior to 8.2. (CVE-2022-0361)

  - Out-of-bounds Read in GitHub repository vim/vim prior to 8.2. (CVE-2022-0368)

  - Heap-based Buffer Overflow in GitHub repository vim prior to 8.2. (CVE-2022-0392)

  - Heap-based Buffer Overflow occurs in vim in GitHub repository vim/vim prior to 8.2.4563. (CVE-2022-0943)

  - Use after free in utf_ptr2char in GitHub repository vim/vim prior to 8.2.4646. (CVE-2022-1154)

  - Use after free in append_command in GitHub repository vim/vim prior to 8.2.4895. This vulnerability is
    capable of crashing software, Bypass Protection Mechanism, Modify Memory, and possible remote execution
    (CVE-2022-1616)

  - NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 in GitHub repository vim/vim
    prior to 8.2.4901. NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 allows
    attackers to cause a denial of service (application crash) via a crafted input. (CVE-2022-1620)
