"The version of Opera installed on the remote host is earlier than 9.63
and thus reportedly affected by several issues :

  - It may be possible to execute arbitrary code on the
    remote system by manipulating certain text-area 
    contents. (920)

  - It may be possible to crash the remote browser using 
    certain HTML constructs or inject code under certain 
    conditions. (921)

  - It may be possible to trigger a buffer overflow, and
    potentially execute arbitrary code, by tricking an 
    user to click on a URL that contains exceptionally 
    long host names. (922)

  - While previewing news feeds, Opera does not correctly
    block certain scripted URLs. Such scripts, if not 
    blocked, may be able to subscribe a user to other 
    arbitrary feeds and view contents of the feeds to which
    the user is currently subscribed. (923)

  - By displaying content using XSLT as escaped strings, it 
    may be possible for a website to inject scripted
    markup. (924)

  - SSL server certificates are not properly validated due
    to an unspecified error. (CVE-2012-1251)" );
