Descriptions

dwarf1.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, mishandles pointers, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted ELF file, related to parse_die and parse_line_table, as demonstrated by a parse_die heap-based buffer over-read.

dwarf1.c en la biblioteca Binary File Descriptor (BFD) (también llamada libbfd), tal y como se distribuye en GNU Binutils 2.29, no gestiona correctamente los punteros. Esto permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) o, posiblemente, otro tipo de impacto sin especificar mediante un archivo ELF. Esto se relaciona con parse_die y parse_line_table, tal y como demuestra una sobrelectura de búfer basada en memoria dinámica (heap).
