Description

An update for vim is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Vim (Vi IMproved) is an updated and improved version of the vi editor.

Security Fix(es) :

  • 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)
