Description Andrej Nemec 2017-04-10 14:34:12 UTC 
The Binary File Descriptor (BFD) library (aka libbfd) has an aout_link_add_symbols function in bfd/aoutx.h that has an off-by-one vulnerability because it does not carefully check the string offset. The vulnerability could lead to a GNU linker (ld) program crash.
