Multiple vulnerabilities in JHead might lead to the execution of arbitrary code or data loss.
JHead is an exif jpeg header manipulation tool.
Marc Merlin and John Dong reported multiple vulnerabilities in JHead:
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 ">=media-gfx/jhead-2.84-r1"
