NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

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.
