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"
