SEC Consult has discovered a buffer overflow in the code
|
|
processing style sheet attributes. It is caused by an integer
|
|
signedness error in a length check followed by a call to a string
|
|
function. It seems to be hard to exploit this buffer overflow to
|
|
execute arbitrary code because of the very large amount memory that has
|
|
to be copied.

|
|
A remote attacker can entice a user to visit a web page containing
|
|
a specially crafted style sheet attribute that will crash the user's
|
|
browser and maybe lead to the execution of arbitrary code.

There is no known workaround at this time.

All Opera users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-client/opera-8.54"</code>
