CVE-2018-10535 Information

Description

The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils 2.30 does not validate the output_section pointer in the case of a symtab entry with a \SECTION\ type that has a \0\ value which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file as demonstrated by objcopy.
