Description Laura Pardo 2018-03-05 18:08:08 EST 
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 remote
attackers to cause a denial of service (integer overflow and application crash)
via an ELF file with corrupted dwarf1 debug information.
