Last modified Jun 17, 2026

CVE-2017-7300 is a vulnerability of currently unknown severity. The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an aout_link_add_symbols function in 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.. EPSS estimates a 2.37% chance of exploitation in the next 30 days.
