Descriptions
A heap-based buffer over-read issue was discovered in the function sec_merge_hash_lookup in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, because _bfd_add_merge_section mishandles section merges when size is not a multiple of entsize. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.
Se ha descubierto un problema de sobrelectura de búfer basada en memoria dinámica (heap) en la función sec_merge_hash_lookup en merge.c en la biblioteca Binary File Descriptor (BFD) (también conocida como libbfd), tal y como se distribuye en GNU Binutils 2.31. Esto se debe a que _bfd_add_merge_section gestiona de manera incorrecta las fusiones de sección cuando el tamaño no es un múltiplo de entsize. Un ELF especialmente manipulado permite que atacantes remotos provoquen una denegación de servicio (DoS), tal y como queda demostrado con Id.
