Google has addressed another zero-day vulnerability in the Chrome browser, tracked as CVE-2024-3159, that was exploited during the Pwn2Own hacking competition in March, 2024.
The vulnerability CVE-2024-3159 is an out of bounds memory access in V8 JavaScript engine. The flaw was demonstrated by Edouard Bochin (@le_douds) and Tao Yan (@Ga1ois) of Palo Alto Networks during the Pwn2Own 2024 on March 22, 2024. The duo earned $42,500 and 9 Master of Pwn points for demonstrating their exploit against Google Chrome and Microsoft Edge.
A remote attacker can exploit this issue by tricking the victim into visiting a specially crafted HTML page to gain access to data beyond the memory buffer triggering heap corruption. The exploitation can lead to the disclosure of sensitive information or a crash.
Palo Alto Networks security researchers Edouard Bochin and Tao Yan demoed the zero-day on the second day of Pwn2Own Vancouver 2024 to defeat V8 hardening.
“The Stable channel has been updated to 123.0.6312.105/.106/.107 for Windows and Mac and 123.0.6312.105 to Linux which will roll out over the coming days/weeks.” reads the Release updates from the Chrome team.
