FAQs regarding Amazon Linux ALAS/CVE Severity
A heap buffer overflow vulnerability was found in vim's ins_compl_infercase_gettext() function of the src/insexpand.c file. This flaw occurs when vim tries to access uninitialized memory when completing a long line. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap-based buffer overflow that causes an application to crash, possibly executing code and corrupting memory. (CVE-2022-2522)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0220. (CVE-2022-2849)
Use After Free in GitHub repository vim/vim prior to 9.0.0221. (CVE-2022-2862)
A heap use-after-free vulnerability was found in vim's qf_fill_buffer() function of the src/quickfix.c file. The issue occurs because vim uses freed memory when recursively using 'quickfixtextfunc.' 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-2022-2982)
A heap use-after-free vulnerability was found in vim's get_next_valid_entry() function of the src/quickfix.c file. The issue occurs because vim is using freed memory when the location list is changed in autocmd. 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-2022-3016)
Use After Free in GitHub repository vim/vim prior to 9.0.0530. (CVE-2022-3256)
Stack-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0598. (CVE-2022-3324)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0742. (CVE-2022-3491)
A null pointer dereference issue was discovered in function gui_x11_create_blank_mouse in gui_x11.c in vim 8.1.2269 thru 9.0.0339 allows attackers to cause denial of service or other unspecified impacts. (CVE-2022-47024)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1144. (CVE-2023-0051)
Out-of-bounds Write in GitHub repository vim/vim prior to 9.0.1145. (CVE-2023-0054)
A heap-based buffer overflow vulnerability was found in GitHub repository vim/vim prior to 9.0.1376 in Vim's utf_ptr2char() function of the src/mbyte.c file. This flaw occurs because there is access to invalid memory with put in visual block mode. An attacker can trick a user into opening a specially crafted file, triggering an out-of-bounds read that causes an application to crash, leading to a denial of service. (CVE-2023-1170)
Incorrect Calculation of Buffer Size in GitHub repository vim/vim prior to 9.0.1378. (CVE-2023-1175)
NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1392. (CVE-2023-1264)
NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1402. (CVE-2023-1355)
