NVD Description

Note: Versions mentioned in the description apply only to the upstream thunderbird package and not the thunderbird package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The mozIJSSubScriptLoader.LoadScript function in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 does not apply XPCNativeWrappers to scripts loaded from (1) file: URIs, (2) data: URIs, or (3) certain non-canonical chrome: URIs, which allows remote attackers to execute arbitrary code via vectors involving third-party add-ons.
