vim is vulnerable to Heap-based Buffer Overflow

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2021-001 advisory.

    A flaw was found in vim. A possible heap-based buffer overflow could allow an attacker to input a     specially crafted file leading to a crash or code execution. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system availability. (CVE-2021-3778)

    A use-after-free vulnerability in vim could allow an attacker to input a specially crafted file leading to     memory corruption and a potentially exploitable crash or code execution. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-3796)

    An out-of-bounds write flaw was found in vim's drawscreen.c win_redr_status() function. This flaw allows     an attacker to trick a user to open a crafted file with specific arguments in vim, triggering an out-of-     bounds write. The highest threat from this vulnerability is to confidentiality, integrity, and system     availability. (CVE-2021-3872)

    There's an out-of-bounds read flaw in Vim's ex_docmd.c. An attacker who is capable of tricking a user into     opening a specially crafted file could trigger an out-of-bounds read on a memmove operation, potentially     causing an impact to application availability. (CVE-2021-3875)

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.

An update of the vim package has been released.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4619-1 advisory.

  - Untrusted search path vulnerability in src/if_python.c in the Python interface in Vim before 7.2.045     allows local users to execute arbitrary code via a Trojan horse Python file in the current working     directory, related to a vulnerability in the PySys_SetArgv function (CVE-2008-5983), as demonstrated by an     erroneous search path for plugin/bike.vim in bicyclerepair. (CVE-2009-0316)

  - vim before patch 8.0.0056 does not properly validate values for the 'filetype', 'syntax' and 'keymap'     options, which may result in the execution of arbitrary code if a file with a specially crafted modeline     is opened. (CVE-2016-1248)

  - fileio.c in Vim prior to 8.0.1263 sets the group ownership of a .swp file to the editor's primary group     (which may be different from the group ownership of the original file), which allows local users to obtain     sensitive information by leveraging an applicable group membership, as demonstrated by /etc/shadow owned     by root:shadow mode 0640, but /etc/.shadow.swp owned by root:users mode 0640, a different vulnerability     than CVE-2017-1000382. (CVE-2017-17087)

  - vim before patch 8.0.0322 does not properly validate values for tree length when handling a spell file,     which may result in an integer overflow at a memory allocation site and a resultant buffer overflow.
    (CVE-2017-5953)

  - An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if     it does not properly validate values for tree length when reading a corrupted undo file, which may lead to     resultant buffer overflows. (CVE-2017-6349)

  - An integer overflow at an unserialize_uep memory allocation site would occur for vim before patch     8.0.0378, if it does not properly validate values for tree length when reading a corrupted undo file,     which may lead to resultant buffer overflows. (CVE-2017-6350)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1567 advisory.

    2024-02-14: CVE-2021-3778 was added to this advisory.

    2024-02-14: CVE-2021-3875 was added to this advisory.

    2024-02-14: CVE-2021-3872 was added to this advisory.

    A flaw was found in vim. A possible heap-based buffer overflow could allow an attacker to input a     specially crafted file leading to a crash or code execution. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system availability. (CVE-2021-3778)

    An out-of-bounds write flaw was found in vim's drawscreen.c win_redr_status() function. This flaw allows     an attacker to trick a user to open a crafted file with specific arguments in vim, triggering an out-of-     bounds write. The highest threat from this vulnerability is to confidentiality, integrity, and system     availability. (CVE-2021-3872)

    There's an out-of-bounds read flaw in Vim's ex_docmd.c. An attacker who is capable of tricking a user into     opening a specially crafted file could trigger an out-of-bounds read on a memmove operation, potentially     causing an impact to application availability. (CVE-2021-3875)

    It was found that vim was vulnerable to use-after-free flaw in the way it was treating allocated lines in     user functions. A specially crafted file could crash the vim process or possibly lead to other undefined     behaviors. (CVE-2022-0156)

    It was found that vim was vulnerable to a 1 byte heap based out of bounds read flaw in the     `compile_get_env()` function. A file could use that flaw to disclose 1 byte of vim's internal memory.
    (CVE-2022-0158)

    A flaw was found in vim.  The vulnerability occurs due to not checking the length for the NameBuff     function, which can lead to a heap buffer overflow. This flaw allows an attacker to input a specially     crafted file, leading to a crash or code execution. (CVE-2022-0213)

    A heap based out-of-bounds write flaw was found in vim's ops.c. This flaw allows an attacker to trick a     user to open a crafted file triggering an out-of-bounds write. This vulnerability is capable of crashing     software, modify memory, and possible code execution. (CVE-2022-0261)

    A flaw was found in vim.  The vulnerability occurs due to reading beyond the end of a line in the     utf_head_off function, which can lead to a heap buffer overflow. This flaw allows an attacker to input a     specially crafted file, leading to a crash or code execution. (CVE-2022-0318)

    A flaw was found in vim. The vulnerability occurs due to too many recursions, which can lead to a     segmentation fault. This flaw allows an attacker to input a specially crafted file, leading to a crash or     code execution. (CVE-2022-0351)

    A flaw was found in vim. The vulnerability occurs due to Illegal memory access with large tabstop in Ex     mode, which can lead to a heap buffer overflow. This flaw allows an attacker to input a specially crafted     file, leading to a crash or code execution. (CVE-2022-0359)
