Detailed vulnerability description
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. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
