CVE-2023-6345: Chrome <119 Sandbox Escape via Skia Integer Overflow
CVE-2023-6345 Published on November 29, 2023
Integer overflow in Skia in Google Chrome prior to 119.0.6045.199 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a malicious file. (Chromium security severity: High)
Known Exploited Vulnerability
This Google Skia Integer Overflow Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Google Skia contains an integer overflow vulnerability affecting Google Chrome and ChromeOS, Android, Flutter, and possibly other products.
The following remediation steps are recommended / required by December 21, 2023: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Vulnerability Analysis
CVE-2023-6345 can be exploited with network access, requires user interaction. This vulnerability is considered to have a low attack complexity. This vulnerability is known to be actively exploited by threat actors in an automatable fashion. The potential impact of an exploit of this vulnerability is considered to be critical as this vulnerability has a high impact to the confidentiality, integrity and availability of this component.
Weakness Type
Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
