GLSA-200606-01 : Opera: Buffer overflow

Medium Nessus Plugin ID 21663


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200606-01 (Opera: Buffer overflow)

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.


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