Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the getvalue function in tekhex.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed when processing a crafted tekhex file, as demonstrated by mishandling within the nm program.
