Synopsis
The remote Amazon Linux 2 host is missing a security update.
Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1805 advisory.
A flaw was found in vim. The vulnerability occurs due to a crash when recording and using Select mode and leads to an out-of-bounds read. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0393)
A flaw was found in vim. The vulnerability occurs due to stack corruption when looking for spell suggestions and leads to a stack buffer overflow. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0408)
A flaw was found in vim. The vulnerability occurs due to using freed memory when the substitute uses a recursive function call, resulting in a use-after-free vulnerability. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0413)
A flaw was found in vim. The vulnerability occurs due to illegal memory access and leads to a heap buffer overflow. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0417)
A flaw was found in vim. The vulnerability occurs due to using freed memory which results in a use-after- free vulnerability. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0443)
A flaw was found in vim that causes an out-of-range pointer offset vulnerability. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0554)
A heap-based buffer overflow flaw was found in vim's ex_retab() function of indent.c file. This flaw occurs when repeatedly using :retab. This flaw allows an attacker to trick a user into opening a crafted file triggering a heap-overflow. (CVE-2022-0572)
A stack-based buffer overflow flaw was found in vim's ga_concat_shorten_esc() function of src/testing.c file. This flaw allows an attacker to trick a user into opening a crafted file, triggering a stack- overflow. This issue can lead to an application crash, causing a denial of service. (CVE-2022-0629)
A flaw was found in vim. The vulnerability occurs due to a crash when using a special multi-byte character and leads to an out-of-range vulnerability. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0685)
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)
A heap-buffer-overflow flaw was found in vim's win_lbr_chartabsize() function of charset.c file. The issue occurs due to an incorrect 'vartabstop' value. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap-overflow, and can cause an application to crash, eventually leading to a denial of service. (CVE-2022-0714)
A flaw was found in vim. The vulnerability occurs due to crashes within specific regexp patterns and strings and leads to an out-of-range vulnerability. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution. (CVE-2022-0729)
A heap buffer overflow flaw was found in vim's suggest_try_change() function of the spellsuggest.c file.
This flaw allows an attacker to trick a user into opening a crafted file, triggering a heap-overflow and causing an application to crash, which leads to a denial of service. (CVE-2022-0943)
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)
A heap buffer overflow flaw was found in vim's get_one_sourceline() function of scriptfile.c file. This flaw occurs when source can read past the end of the copied line. This flaw allows an attacker to trick a user into opening a crafted file, triggering a heap-overflow and causing an application to crash, which leads to a denial of service. (CVE-2022-1160)
A global heap buffer overflow vulnerability was found in vim's skip_range() function of the src/ex_docmd.c file. This flaw occurs because vim uses an invalid pointer with V: in Ex mode. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap buffer overflow that causes an application to crash, leading to a denial of service. (CVE-2022-1381)
A vulnerability was found in Vim. The issue occurs when using a number in a string for the lambda name, triggering an out-of-range pointer offset vulnerability. This flaw allows an attacker to trick a user into opening a crafted script containing an argument as a number and then using it as a string pointer to access any memory location, causing an application to crash and possibly access some memory.
(CVE-2022-1420)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'yum update vim' to update your system.
