CVE-2018-7568: Integer Overflow
First published: Wed Feb 28 2018(Updated: )
A flaw was found in the parse_die function in dwarf1.c 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 vulnerability allows attackers to cause a denial of service (integer overflow and application crash) via an ELF file with corrupted dwarf1 debug information.
