Description Pedro Sampaio 2017-08-23 19:19:37 UTC 
The getsym function in tekhex.c in the Binary File Descriptor (BFD) library (aka
libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a
denial of service (stack-based buffer over-read and application crash) via a
malformed tekhex binary.
