Two Severe Flaws In Opera Browser
Opera has warned of two severe bugs in its browser, which could allow attackers to invade a system via simple elements embedded in web pages.
The first bug involves the browser’s handling of HTML 5 canvas elements, which allow dynamic rendering of bitmap images that can be scripted.
If an image is scaled in a particular way, it can cause the browser to crash, which can cause memory corruption. Opera classified the bug “moderately severe.”
The second bug involves Opera’s handling of news feed sources.
When the browser encounters a feed source, it normally triggers a user prompt, but a specially crafted source could be exploited to cause an invalid memory access and crash the browser. This bug is ranked “highly severe.”
Both bugs can be used to exploit malicious code on a system and they both are fixed in the new browser version, 9.27.
