Description

The nsXBLProtoImpl::InstallImplementation function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 does not properly check whether objects are XBL objects, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted JavaScript code that accesses a non-XBL object as if it were an XBL object.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 2.26
Affected range stops below 2.26, so it looks safe — our inference, not a vendor statement
v < 24.5
Affected range stops below 24.5, so it looks safe — our inference, not a vendor statement
