Detailsinfo

A vulnerability has been found in GNU binutils 2.28 (Programming Tool Software) and classified as critical. This vulnerability affects an unknown part of the file opcodes/rx-decode.opc. The manipulation as part of a Binary File leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

opcodes/rx-decode.opc in GNU Binutils 2.28 lacks bounds checks for certain scale arrays, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file during "objdump -D" execution.

The bug was discovered 06/13/2017. The weakness was presented 06/19/2017 by Alex as Bug 21587 as confirmed bug report (Bugzilla). The advisory is available at sourceware.org.
