Updates at the moment are accessible to patch a Chrome vulnerability that may enable attackers to run malicious code.
It’s time to replace Google Chrome, Mozilla’s Firefox or Thunderbird, Microsoft Edge, the Courageous browser or Tor Browser; internet growth information website StackDiary has reported a zero-day vulnerability in all six browsers that might enable risk actors to execute malicious code.
Vulnerability originates in WebP reader
Customers of the affected browsers ought to replace to probably the most up-to-date model with the intention to make sure the zero-day vulnerability is patched on their machines. The issue isn’t with the browsers — the vulnerability originates within the WebP Codec, StackDiary found.
Different affected functions embrace:
- Many Android functions.
- Cross-platform apps constructed with Flutter.
Apps constructed on Electron may additionally be affected; Electron launched a patch.
Many functions use the WebP codec and libwebp library to render WebP photographs, StackDiary famous.

In additional element, a heap buffer overflow in WebP allowed attackers to carry out an out-of-bounds reminiscence write, NIST stated. A heap buffer overflow permits attackers to insert malicious code by “overflowing” the quantity of knowledge in a program, StackDiary defined. Since this specific heap buffer overflow targets the codec (basically a translator that lets a pc render WebP photographs), the attacker may create a picture during which malicious code is embedded. From there, they may steal information or infect the pc with malware.
The vulnerability was first detected by the Apple Safety Engineering and Structure group and The Citizen Lab at The College of Toronto on September 6, StackDiary stated.
What steps ought to customers take?
Google, Mozilla, Courageous, Microsoft and Tor have launched safety patches for this vulnerability. People operating these apps ought to replace to the newest model. Within the case of different functions, that is an ongoing vulnerability for which patches might not exist; NIST famous that the vulnerability has not but acquired full evaluation.
NIST categorized the vulnerability as extreme and recommends customers cease utilizing functions for which a patch isn’t but accessible. Test your utility individually as wanted.
