- ------------------------------------------------------------------------- Debian Security Advisory DSA-6003-1 [email protected] https://www.debian.org/security/ Moritz Muehlenhoff September 18, 2025 https://www.debian.org/security/faq
- -------------------------------------------------------------------------

Package : firefox-esr CVE ID : CVE-2025-10527 CVE-2025-10528 CVE-2025-10529 CVE-2025-10532 CVE-2025-10533 CVE-2025-10536 CVE-2025-10537

Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code, sandbox escape, information disclosure or bypass of the same-origin policy.

Debian follows the extended support releases (ESR) of Firefox.
So starting with this update we're now following the 140.x releases.

Between 128.x and 140.x, Firefox has seen a number of feature updates. For more information please refer to https://www.firefox.com/en-US/firefox/140.0esr/releasenotes/

For the oldstable distribution (bookworm), these problems have been fixed in version 140.3.0esr-1~deb12u1.

For the stable distribution (trixie), these problems have been fixed in version 140.3.0esr-1~deb13u1.

We recommend that you upgrade your firefox-esr packages.

For the detailed security status of firefox-esr please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/firefox-esr
