# Integer overflow in Skia in Google Chrome prior to 119.0.6045.199 allowed a remote attacker who had compromised the…

Skia, the 2D graphics library inside Google Chrome, ChromeOS, Android and Flutter, has an integer overflow. A remote attacker who has already compromised the renderer process can use a malicious file to escape the browser sandbox.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Google Chromium Skia affected ? fixed ?
- vendor:google chrome affected < 119.0.6045.199 fixed 119.0.6045.199
- vendor:debian linux affected = 11.0 fixed ?
- vendor:debian linux affected = 12.0 fixed ?
- vendor:fedoraproject fedora affected = 37 fixed ?
- vendor:fedoraproject fedora affected = 38 fixed ?
- vendor:fedoraproject fedora affected = 39 fixed ?
- vendor:microsoft edge chromium affected < 119.0.2151.97 fixed 119.0.2151.97

## Fix

Update Google Chrome, ChromeOS, Android or Flutter to a build that includes the vendor fix; the sources do not name fixed versions. Follow the vendor instructions referenced by CISA.

## From the sources

Google Chromium Skia contains an integer overflow vulnerability that allows a remote attacker, who has compromised the renderer process, to potentially perform a sandbox escape via a malicious file. This vulnerability affects Google Chrome and ChromeOS, Android, Flutter, and possibly other products.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
