CVSS v3.1
8.8
High
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Google Chrome versions prior to 88.0.4324.150
Description:
A heap buffer overflow in the V8 JavaScript engine allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. This issue was actively exploited in the wild. The vulnerability is described as a heap-based buffer overflow, which could allow for the execution of arbitrary code.
Recommendations:
For Google Chrome versions prior to 88.0.4324.150, update to version 88.0.4324.150 or later to resolve the issue. As a temporary workaround, consider avoiding the use of potentially vulnerable JavaScript functions until a patch is applied. Restrict access to untrusted HTML pages to minimize the risk of exploitation. At the moment, there is no additional information about other mitigation measures.
