Detailsinfo

A vulnerability was found in GNU binutils 2.28 (Programming Tool Software). It has been classified as problematic. Affected is some unknown functionality of the component BFD Library. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. CVE summarizes:

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 1 because the existing reloc offset range tests didn't catch small negative offsets less than the size of the reloc field. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library, such as objdump, to crash.

The bug was discovered 05/01/2017. The weakness was presented 05/01/2017 as Bug 21432 as not defined bug report (Bugzilla). The advisory is shared for download at sourceware.org.
