Summary of Meeting Notes:
– Google fixed a zero-day vulnerability (CVE-2024-3159) in the Chrome browser related to an out-of-bounds read weakness in the Chrome V8 JavaScript engine.
– Remote attackers could exploit the vulnerability using crafted HTML pages to gain access to data beyond the memory buffer, potentially leading to sensitive information leakage or a system crash.
– Security researchers demoed the zero-day exploit at Pwn2Own Vancouver 2024, and Google has now released fixes for the vulnerability in Google Chrome stable channel versions.
– Earlier, Google also fixed two other Chrome zero-days (CVE-2024-2887 and CVE-2024-2886) exploited at Pwn2Own Vancouver 2024, while Mozilla patched two Firefox zero-days.
– Vendors typically take time to fix Pwn2Own zero-days since bug details are publicly disclosed after 90 days by Trend Micro’s Zero Day Initiative.
– In total, Google patched four Chrome zero-days this year, with the fourth addressed in January.
– Additionally, Google fixed two Android zero-days exploited by forensic firms.
