CVE-2024-47541

GStreamer is a library for constructing graphs of media-handling components. An OOB-write vulnerability has been identified in the gst_ssa_parse_remove_override_codes function of the gstssaparse.c file. This function is responsible for parsing and removing SSA (SubStation Alpha) style override codes, which are enclosed in curly brackets ({}). The issue arises when a closing curly bracket "}" appears before an opening curly bracket "{" in the input string. In this case, memmove() incorrectly duplicates a substring. With each successive loop iteration, the size passed to memmove() becomes progressively larger (strlen(end+1)), leading to a write beyond the allocated memory bounds. This vulnerability is fixed in 1.24.10.

Summary		(es) GStreamer es una librería para construir gráficos de componentes de manejo de medios. Se ha identificado una vulnerabilidad de escritura OOB en la función gst_ssa_parse_remove_override_codes del archivo gstssaparse.c. Esta función es responsable de analizar y eliminar los códigos de anulación de estilo SSA (SubStation Alpha), que están encerrados entre llaves ({}). El problema surge cuando aparece una llave de cierre "}" antes de una llave de apertura "{" en la cadena de entrada. En este caso, memmove() duplica incorrectamente una subcadena. Con cada iteración sucesiva del bucle, el tamaño pasado a memmove() se vuelve progresivamente más grande (strlen(end+1)), lo que lleva a una escritura más allá de los límites de memoria asignados. Esta vulnerabilidad se corrigió en 1.24.10.
