Beskrivelse:
Parvez Anwar har fundet en sårbarhed i Yahoo! Widgets, som kan udnyttes af ondsindede personer til at kompromittere en brugers system.

Sårbarheden skyldes en ikke-kontrolleret buffer i YDPCTL.YDPControl.1 (YDPCTL.dll) ActiveX-kontrollen under håndteringen af "GetComponentVersion()" metoden. Dette kan udnyttes til at forårsage et stack-baseret buffer overflow ved at supplere en lang streng (mere end 512 bytes) til metoden.

Succesfuld udnyttelse muliggør eksekvering af vilkårlig kode.

Sårbarheden er bekræftet i YDPCTL.dll version 2007.4.13.1 inkluderet i Yahoo! Widgets version 4.0.3 (build 178). Andre versioner kan også være berørte.
