Beskrivelse:
Der er fundet en sårbarhed i Mozilla Firefox, som kan udnyttes af ondsindede personer til at få kendskab til potentielt følsom information.

Sårbarheden skyldes en fejl i JavaScript enginen, eftersom en "lambda" replace afslører en vilkårlig mængde heap-hukommelse efter enden på en JavaScript-streng.

Succesfuld udnyttelse kan afsløre følsom information i hukommelsen.

Secunia har konstrueret en test, som kan benyttes til at teste, om en browser er sårbar:

Sårbarheden er bekræftet i version 1.0.1 og 1.0.2, men andre versioner kan også være berørte.

Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.

Løsning:
Opdatér til version 1.0.3.
