+ <title>Opera: Buffer overflow</title>
+ <synopsis>
+ Opera contains an integer signedness error resulting in a buffer overflow
+ which may allow a remote attacker to execute arbitrary code.

+ <p>
+ Opera is a multi-platform web browser.

+ <description>
+ <p>
+ 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.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Opera users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=www-client/opera-8.54"</code>
