Description Andrej Nemec 2017-04-10 14:39:19 UTC 
The Binary File Descriptor (BFD) library (aka libbfd) is vulnerable to an invalid read (of size 8) because of missing a check (in the copy_special_section_fields function) for an invalid sh_link field before attempting to follow it. This vulnerability causes Binutils utilities like strip to crash.
