Synopsis
========
Multiple vulnerabilities in JHead might lead to the execution of
arbitrary code or data loss.
Background
==========
JHead is an exif jpeg header manipulation tool.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/jhead < 2.84-r1 >= 2.84-r1
Description
===========
Marc Merlin and John Dong reported multiple vulnerabilities in JHead:
* A buffer overflow in the DoCommand() function when processing the
cmd argument and related to potential string overflows
(CVE-2008-4575).
* An insecure creation of a temporary file (CVE-2008-4639).
* A error when unlinking a file (CVE-2008-4640).
* Insufficient escaping of shell metacharacters (CVE-2008-4641).
Impact
======
A remote attacker could possibly execute arbitrary code by enticing a
user or automated system to open a file with a long filename or via
unspecified vectors. It is also possible to trick a user into deleting
or overwriting files.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All JHead users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/jhead-2.84-r1"
