RHEL 5 : vim (Unpatched Vulnerability)

critical Nessus Plugin ID 196373

Synopsis

The remote Red Hat 5 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - vim: Integer overflow at an unserialize_uep memory allocation site (CVE-2017-6350)

 - 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)

 - VIM version 8.0.1187 (and other versions most likely) ignores umask when creating a swap file ([ORIGINAL_FILENAME].swp) resulting in files that may be world readable or otherwise accessible in ways not intended by the user running the vi binary. (CVE-2017-1000382)

 - Vim 8.0 allows attackers to cause a denial of service (invalid free) or possibly have unspecified other impact via a crafted source (aka -S) file. NOTE: there might be a limited number of scenarios in which this has security relevance. (CVE-2017-11109)

 - 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)

 - In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua). (CVE-2019-20807)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
