Detailsinfo

A vulnerability, which was classified as problematic, has been found in GNU binutils 2.28 (Programming Tool Software). This issue affects the function aout_link_add_symbols of the file bfd/aoutx.h of the component BFD Library. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h that has an off-by-one vulnerability because it does not carefully check the string offset. The vulnerability could lead to a GNU linker (ld) program crash.

The bug was discovered 12/06/2016. The weakness was published 03/29/2017 as Bug 20924 as not defined bug report (Bugzilla). The advisory is shared at sourceware.org.
