Description

The score_opcodes function in opcodes/score7-dis.c in GNU Binutils 2.28 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.

In plain language

AI Worth attention

CVE-2017-9742 is a GNU Binutils crash bug you can trigger by opening a specially crafted binary file in `objdump -D`; if your business runs `objdump` on untrusted files, you should act, but normal office use isn’t automatically exposed.

Executive summary

CVE-2017-9742 is a denial-of-service buffer overflow in `score_opcodes` (opcodes/score7-dis.c) in GNU Binutils 2.28, triggered when a user runs `objdump -D` on a crafted binary file; affected systems are only at risk if that disassembly path is used on attacker-supplied files.
