Detailsinfo

A vulnerability, which was classified as critical, has been found in GNU binutils 2.28 (Programming Tool Software). Affected by this issue is the function getvalue of the file tekhex.c of the component libbfd. The manipulation as part of a File Descriptor leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.
