(zoo: Stack-based buffer overflow)

    Jean-Sebastien Guay-Leroux discovered a boundary error in the
    fullpath() function in misc.c when processing overly long file and
    directory names in ZOO archives.
  
Impact :

    An attacker could craft a malicious ZOO archive and entice someone
    to open it using zoo. This would trigger a stack-based buffer overflow
    and potentially allow execution of arbitrary code with the rights of
    the victim user.
  
Workaround :

    There is no known workaround at this time."
