Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of thunderbird installed on the remote host is prior to 128.11.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2873 advisory.

An attacker was able to perform an out-of-bounds read or write on a JavaScript `Promise` object. This vulnerability affects Firefox < 138.0.4, Firefox ESR < 128.10.1, and Firefox ESR < 115.23.1.
(CVE-2025-4918)

An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes. This vulnerability affects Firefox < 138.0.4, Firefox ESR < 128.10.1, and Firefox ESR < 115.23.1. (CVE-2025-4919)

Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. (CVE-2025-5263)

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.
This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. (CVE-2025-5264)

Due to insufficient escaping of the ampersand 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.*This bug only affects Firefox for Windows. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. (CVE-2025-5265)

Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11.
(CVE-2025-5266)

A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11. (CVE-2025-5267)

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. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11. (CVE-2025-5268)

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. This vulnerability affects Firefox ESR < 128.11. (CVE-2025-5269)

Use after free in libvpx in Google Chrome prior to 137.0.7151.55 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
