Descriptions

The *_get_synthetic_symtab functions in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, do not ensure a unique PLT entry for a symbol, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted ELF file, related to elf32-i386.c and elf64-x86-64.c.

Las funciones *_get_synthetic_symtab en la biblioteca Binary File Descriptor (BFD) (también llamada libbfd), tal y como se distribuye en GNU Binutils 2.29 no aseguran una entrada PLT única para un símbolo. Esto permite que los atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en memoria dinámica o heap y cierre inesperado de la aplicación) o que tengan otro impacto sin especificar mediante un archivo ELF manipulado, relacionado con elf32-i386.c y elf64-x86-64.c.
