Slackware Linux 15.0 / current mozilla-firefox Multiple Vulnerabilities (SSA:2023-185-01)

high Nessus Plugin ID 177937


The remote Slackware Linux host is missing a security update to mozilla-firefox.


The version of mozilla-firefox installed on the remote host is prior to 102.13.0esr / 115.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-185-01 advisory.

- An attacker could have triggered a use-after-free condition when creating a WebRTC connection over HTTPS.

- Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free. (CVE-2023-37202)

- A website could have obscured the fullscreen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks. (CVE-2023-37207)

- When opening Diagcab files, Firefox did not warn the user that these files may contain malicious code.

- Memory safety bugs present in Firefox 114, Firefox ESR 102.12, and Thunderbird 102.12. 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-2023-37211)

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


Upgrade the affected mozilla-firefox package.
