    It was found that vim was vulnerable to use-after-free flaw in win_linetabsize(). Sourcing a specially     crafted file in vim could crash the vim process or possibly lead to other undefined behaviors.
    (CVE-2021-4192)

    It was found that vim was vulnerable to an out-of-bound read flaw in getvcol(). A specially crafted file     could be used to, when opened in vim, disclose some of the process's internal memory. (CVE-2021-4193)

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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2021-005 advisory.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - vim is vulnerable to Heap-based Buffer Overflow (CVE-2021-3903)

Note that Nessus relies on the presence of the package as reported by the vendor.

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

  - vim is vulnerable to Heap-based Buffer Overflow (CVE-2021-3872, CVE-2021-3875, CVE-2021-3903,     CVE-2021-3927)

  - vim is vulnerable to Use of Uninitialized Variable (CVE-2021-3928)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2102-1 advisory.

  - 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.
