Synopsis

A vulnerability in file could result in Denial of Service.

Background

file is a utility that guesses a file format by scanning binary data for
patterns.

Unaffected: >= 5.15
Architectures: All supported architectures


Description

magic/Magdir/commands uses multiple wildcards with unlimited repetitions.


Impact

A context-dependent attacker could entice a user to open a specially
crafted file,
possibly resulting in a Denial of Service condition.


Workaround

There is no known workaround at this time.

Resolution

Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/file-5.15"
