FreeBSD : Mozilla -- multiple vulnerabilities (085101eb-f212-11f0-9ca3-b42e991fc52e)

critical Nessus Plugin ID 291282

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 085101eb-f212-11f0-9ca3-b42e991fc52e advisory.

 Memory safety bugs present in firefox-esr 140.6, Thunderbird ESR 140.6, Firefox 146 and Thunderbird 146.
 Spoofing issue in the DOM: Copy & Paste and Drag & Drop component.
 Clickjacking issue and information disclosure in the PDF Viewer component.
 Use-after-free in the JavaScript: GC component.
 Use-after-free in the JavaScript Engine component.
 Information disclosure in the Networking component.
 Sandbox escape due to incorrect boundary conditions in the Graphics: CanvasWebGL component.

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

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

Solution

Update the affected packages.
