Description

Updated nss & firefox packages fix security vulnerabilities CVE-2025-5263: Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. CVE-2025-5264: Due to insufficient escaping of the newline character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. CVE-2025-5266: Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. CVE-2025-5267: A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. CVE-2025-5268: Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. 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. CVE-2025-5269: Memory safety bug present in Firefox ESR 128.10, and Thunderbird 128.10. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. We can't ship this update to armv7hl architecture; we are investigating the issue and will try to update firefox for armv7hl as soon as possible.
