According to the versions of the vim packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • Heap buffer overflow in vim_strncpy find_word in GitHub repository vim/vim prior to 8.2.4919. This vulnerability is capable of crashing software, Bypass Protection Mechanism, Modify Memory, and possible remote execution (CVE-2022-1621)

  • Buffer Over-read in function find_next_quote in GitHub repository vim/vim prior to 8.2.4925. This vulnerabilities are capable of crashing software, Modify Memory, and possible remote execution (CVE-2022-1629)

  • NULL Pointer Dereference in function vim_regexec_string at regexp.c:2733 in GitHub repository vim/vim prior to 8.2.4938. NULL Pointer Dereference in function vim_regexec_string at regexp.c:2733 allows attackers to cause a denial of service (application crash) via a crafted input. (CVE-2022-1674)

  • Heap-based Buffer Overflow in GitHub repository vim/vim prior to 8.2.4968. (CVE-2022-1733)

  • Classic Buffer Overflow in GitHub repository vim/vim prior to 8.2.4969. (CVE-2022-1735)

  • Uncontrolled Recursion in GitHub repository vim/vim prior to 8.2.4975. (CVE-2022-1771)

  • Out-of-bounds Write in GitHub repository vim/vim prior to 8.2.4977. (CVE-2022-1785)

  • Use After Free in GitHub repository vim/vim prior to 8.2.4979. (CVE-2022-1796)

  • Out-of-bounds Read in GitHub repository vim/vim prior to 8.2. (CVE-2022-1851)

  • Out-of-bounds Write in GitHub repository vim/vim prior to 8.2. (CVE-2022-1897, CVE-2022-2000)

  • Use After Free in GitHub repository vim/vim prior to 8.2. (CVE-2022-1898, CVE-2022-1968)

  • Buffer Over-read in GitHub repository vim/vim prior to 8.2. (CVE-2022-1927)

  • Heap-based Buffer Overflow in GitHub repository vim/vim prior to 8.2. (CVE-2022-1942)
