[GLSA-200606-01] Opera: Buffer overflow |
||
Opera: Buffer overflow Detailed Explanation for this Vulnerability Assessment 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.
