JHead is an exif jpeg header manipulation tool.
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 type="normal">
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.
There is no known workaround at this time.
All JHead users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/jhead-2.84-r1&quot;</code>
