Opera before 9.23 allows remote attackers to execute arbitrary code via crafted Javascript that triggers a "virtual function call on an invalid pointer."

This update of opera fixes a security vulnerabilities that allowed the execution of arbitrary code by using JavaScript. (CVE-2007-4367)

The remote host is affected by the vulnerability described in GLSA-200708-17 (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.

The version of Opera installed on the remote host reportedly allows for execution of arbitrary code via specially-crafted Javascript if a user can be tricked into visiting a malicious site.
