"The version of the HPTicketMgr.dll ActiveX control, part of HP Easy
Printer Care Software and installed on the remote Windows host, is
affected by several vulnerabilities :

  - The 'SaveXML()' method in the XMLSimpleAccessor class
    ActiveX control is prone to a directory traversal
    attack and can be abused to write arbitrary files to the
    system and then execute them through the browser.
    (CVE-2011-2404)

  - The 'CacheDocumentXMLWithId()' method in the XMLCacheMgr
    class ActiveX control is prone to a directory traversal
    attack and can be abused to write malicious content to
    the filesystem. (CVE-2011-4786)

  - The 'LoadXML()' method in the XMLSimpleAccessor class
    ActiveX control is affected by a heap-based buffer
    overflow vulnerability. (CVE-2011-4787)

If an attacker can trick a user on the affected host into visiting a
specially crafted web page, these issues could be leverage to execute
arbitrary code on the host subject to the user's privileges."
