## Description

The \*\_get\_synthetic\_symtab functions in the Binary File Descriptor (BFD)
library (aka libbfd), as distributed in GNU Binutils 2.29, interpret a -1
value as a sorting count instead of an error flag, which allows remote
attackers to cause a denial of service (integer 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.
