CVE-2017-14745 Information

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.
