Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

iDefense Labs reports :

Remote exploitation of a heap overflow vulnerability within version 9
of Opera Software's Opera Web browser could allow an attacker to
execute arbitrary code on the affected host.

A flaw exists within Opera when parsing a tag that contains a URL. A
heap buffer with a constant size of 256 bytes is allocated to store
the URL, and the tag's URL is copied into this buffer without
sufficient bounds checking of its length.
