Package : firefox-esr
Version : 102.3.0esr-1~deb10u2
CVE ID : CVE-2022-40956 CVE-2022-40957 CVE-2022-40958 CVE-2022-40959
CVE-2022-40960 CVE-2022-40962

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

This update brings back support for the i386 and arm64 architectures.
Support for the armhf architecture is still missing, pending some changes
to the buildd network.

For Debian 10 buster, these problems have been fixed in version
102.3.0esr-1~deb10u2.

We recommend that you upgrade your firefox-esr packages.
