  script_tag(name:"insight", value:"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)

A heap use-after-free vulnerability was found in Vim's utf_ptr2char() function of the src/mbyte.c file. This flaw occurs because vim is using a buffer line after it has been freed in the old regexp engine. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap use-after-free that causes an application to crash, possibly executing code and corrupting memory.(CVE-2022-1154)

Heap-based Buffer Overflow in function cmdline_erase_chars in GitHub repository vim/vim prior to 8.2.4899. These vulnerabilities are capable of crashing software, modify memory, and possible remote execution(CVE-2022-1619)

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)

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)

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

A NULL pointer dereference flaw was found in vim's vim_regexec_string() function in regexp.c file. The issue occurs when the function tries to match the buffer with an invalid pattern. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a NULL pointer dereference that causes an application to crash, leading to a denial of service.(CVE-2022-1674)

A NULL pointer dereference flaw was found in vim's find_ucmd() function of usercmd.c file. This flaw allows an attacker to trick a user into opening a crafted file, triggering a NULL pointer dereference. This issue leads to an application crash, causing a denial of service.(CVE-2022-0696)");
