Impact:
A user may be able to execute arbitrary code on the target system.
|
Solution:
Gentoo has released a fix and indicates that all file users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/file-4.12"

Synopsis
========
The code for parsing ELF headers in file contains a flaw which may
allow an attacker to execute arbitrary code.
Background
==========
file is a utility used to identify the type of a file.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/file < 4.12 >= 4.12
Description
===========
A possible stack overflow has been found in the ELF header parsing code
of file.
Impact
======
An attacker may be able to create a specially crafted ELF file which,
when processed with file, may allow the execution of arbitrary code.
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-4.12"
