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"
