Most of the low-severity bugs were insufficient policy enforcements too, complemented by several inappropriate implementations, uninitialized use in WebRTC, and use-after-free in V8. Google says it paid over $26,000 in bug bounty rewards to the reporting security researchers, but the company has yet to disclose the exact amount it awarded for all of the externally reported vulnerabilities.
Mozilla, which revisited the previous decision to disable TLS 1.0 and 1.1 in its browser, this week pushed Firefox 75 to the stable channel, packing it with six security patches for the desktop, and two patches targeting vulnerabilities specific to the Android platform.
A total of three high-severity vulnerabilities were addressed in Firefox 75, two of which could lead to arbitrary code execution, Mozilla says.
The remaining two high-risk bugs could be exploited to leak sensitive data, or to trick the mobile browser into displaying the incorrect URI. The remaining three vulnerabilities feature a moderate severity rating, but one of them could lead to code execution as well.
"Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open. Subsequently, if the user had opened a new Private Browsing Window, revisited the same site, and generated a new password - the generated passwords would have been identical, rather than independent," Mozilla explains.
