Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the bfd/aoutx.h that is vulnerable to a heap-based buffer over-read (off-by-one) because of an incomplete check for invalid string offsets while loading symbols, leading to a GNU linker (ld) program crash within the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28,. A remote attacker can generate specially crafted data, trigger out-of-bounds read error and perform denial of service attack.
