(Opera: Multiple vulnerabilities)

    An error known as 'a virtual function call on an invalid pointer' has
    been discovered in the JavaScript engine (CVE-2007-4367). Furthermore,
    iDefense Labs reported that an already-freed pointer may be still used
    under unspecified circumstances in the BitTorrent support
    (CVE-2007-3929). At last, minor other errors have been discovered,
    relative to memory read protection (Opera Advisory 861) and URI
    displays (CVE-2007-3142, CVE-2007-3819).
  
Impact :

    A remote attacker could trigger the BitTorrent vulnerability by
    enticing a user into starting a malicious BitTorrent download, and
    execute arbitrary code through unspecified vectors. Additionally, a
    specially crafted JavaScript may trigger the 'virtual function'
    vulnerability. The JavaScript engine can also access previously freed
    but uncleaned memory. Finally, a user can be fooled with a too long
    HTTP server name that does not fit the dialog box, or a URI containing
    whitespaces.
  
Workaround :

    There is no known workaround at this time for all these
    vulnerabilities."
