Package : firefox-esr
Version : 115.3.0esr-1~deb10u1
CVE ID : CVE-2023-5169 CVE-2023-5171 CVE-2023-5176

Multiple security issues have been found in the Mozilla Firefox web
browser, which could potentially result in the execution of arbitrary
code.

Debian follows the extended support releases (ESR) of Firefox. Support
for the 102.x series has ended, so starting with this update we're now
following the 115.x releases.

Between 102.x and 115.x, Firefox has seen a number of feature updates.
For more information please refer to
https://www.mozilla.org/en-US/firefox/115.0esr/releasenotes/

For Debian 10 buster, these problems have been fixed in version
115.3.0esr-1~deb10u1.

We recommend that you upgrade your firefox-esr packages.
