Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and Thunderbird 115.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2.

Beyond the WebP Flaw | An In-depth Look at 2023's Browser Security Challenges
This week, Firefox users were urged to apply Mozilla’s latest updates against a critical flaw that could allow attackers to take control of affected systems. It follows hard on the heels of similar updates for Microsoft Edge, Google Chrome, and Apple’s Safari browser. All have been heavily impacted by an actively exploited vulnerability in the WebP code library.
Although the WebP vulnerability affects other software as well, browsers are by far and away the most ubiquitous and widely used applications on end user devices . Having a foothold in a compromised browser gives threat actors access to sensitive information and potential avenues into targeted environments.
