Descriptions
A use-after-free issue was discovered in libwebm through 2018-02-02. If a Vp9HeaderParser was initialized once before, its property frame_ would not be changed because of code in vp9parser::Vp9HeaderParser::SetFrame. Its frame_ could be freed while the corresponding pointer would not be updated, leading to a dangling pointer. This is related to the function OutputCluster in webm_info.cc.
Se ha descubierto una vulnerabilidad de uso de memoria previamente liberada en libwebm hasta el 02-02-2018. Si un Vp9HeaderParser se inicializaba una vez antes, su propiedad frame_ no se cambiaría a causa del código en vp9parser::Vp9HeaderParser::SetFrame. Su frame_could se liberaría y el puntero correspondiente no se actualizaría, provocando un puntero colgante. Esto está relacionado con la función OutputCluster en webm_info.cc.
