Description Laura Pardo 2018-03-05 23:20:30 UTC
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.
