Synopsis
========
A stack-based buffer overflow was found in file, possibly resulting in
the execution of arbitrary code.
Background
==========
file is a utility that guesses a file format by scanning binary data
for patterns.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========
An issue discovered in file allows attackers to write 20 bytes to the
stack buffer via a specially crafted .notes section.
Impact
======
A remote attacker, by using a specially crafted .notes section in an
ELF binary, could execute arbitrary code or cause a Denial of Service
condition.
Workaround
==========
There is no known workaround at this time.
Resolution

All file users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/file-5.32"
