[GLSA-200606-01] Opera: Buffer overflow Vulnerability Scan
Vulnerability Scan Summary
Opera: Buffer overflow
Detailed Explanation for this Vulnerability Test
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.
