Synopsis ========
Opera contains an integer signedness error resulting in a buffer overflow which may allow a remote attacker to execute arbitrary code.
Background ==========
Opera is a multi-platform web browser.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 8.54 >= 8.54
Description ===========
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.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Opera users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-8.54"
