Descriptions

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.

En elfutils 0.175, existe una sobrelectura de búfer basada en memoria dinámica (heap) en la función elf32_xlatetom en elf32_xlatetom.c. Una entrada ELF manipulada puede provocar un fallo de segmentación que conduce a una denegación de servicio (cierre inesperado del programa) debido a que ebl_core_note no rechaza las notas de archivo core mal formadas.
