CVE-2018-7569: Integer Overflow
First published: Wed Feb 28 2018(Updated: )
A flaw was found in the read_attribute_value function in dwarf2.c file in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils up to version 2.30, when compiled in 32bit mode. This allows attackers to cause a denial of service (integer wraparound and application crash) via an ELF file with a corrupt DWARF FORM block.
