CVE-2017-9954
Published: 26 June 2017
The getvalue function in tekhex.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted tekhex file, as demonstrated by mishandling within the nm program.
