Bugs:	#242702, #243238
ID:	200901-02

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	Architecture(s)
media-gfx/jhead	< 2.84-r1	>= 2.84-r1	All supported architectures

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"
