Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unspecified vulnerability in Mozilla Firefox before 2.0.0.13, Thunderbird before 2.0.0.13, and SeaMonkey before 1.1.9 allows remote attackers to execute arbitrary code via "XPCNativeWrapper pollution."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a JavaScript security bypass vulnerability in Mozilla products where XPCNativeWrapper (a security mechanism that isolates privileged code) can be polluted/corrupted by attackers, allowing arbitrary code execution. The vulnerability is triggered when a user visits a malicious webpage.

MitigationUpgrade to Firefox 2.0.0.13+, Thunderbird 2.0.0.13+, or SeaMonkey 1.1.9+ to obtain the patched version. This is a straightforward version update with no configuration changes required.
