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.

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

  - 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)

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

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.

The remote host is affected by the vulnerability described in GLSA-201706-26 (Vim, gVim: Remote execution of arbitrary code)

    Multiple vulnerabilities have been discovered in Vim and gVim. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted spell       file using Vim or gVim, possibly resulting in execution of arbitrary code       with the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

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

  - A vulnerability was found in vim in how certain     modeline options were treated. An attacker could craft     a file that, when opened in vim with modelines enabled,     could execute arbitrary commands with privileges of the     user running vim. (CVE-2016-1248)

  - 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)

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.

An integer overflow flaw was found in the way vim handled tree length values when reading an undo file. This bug could result in vim crashing when trying to process corrupted undo files. (CVE-2017-6350)

This update for vim fixes the following issues :

  - CVE-2017-5953: Fixed a possible overflow with corrupted     spell file (bsc#1024724)

Editor spell files passed to the vim (Vi IMproved) editor may result in an integer overflow in memory allocation and a resulting buffer overflow which potentially could result in the execution of arbitrary code or denial of service.

A vulnerability has been discovered in Vim where a malformed spell file could cause an integer overflow which is used as the size for memory allocation, resulting in a subsequent buffer overflow.

For Debian 7 'Wheezy', these problems have been fixed in version 2:7.3.547-7+deb7u2.

We recommend that you upgrade your vim packages.
