Detailsinfo

A vulnerability, which was classified as critical, was found in GNU binutils 2.28 (Programming Tool Software). This affects some unknown functionality of the file opcodes/bfin-dis.c. The manipulation as part of a Binary File leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The *regs* macros in opcodes/bfin-dis.c in GNU Binutils 2.28 allow 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 disclosed 06/19/2017 by Alex as Bug 21586 as confirmed bug report (Bugzilla). The advisory is shared at sourceware.org. This vulnerability is uniquely identified as CVE-2017-9749 since 06/18/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details and a public exploit are known.

A public exploit has been developed by Alexandre Adamski and been published immediately after the advisory. The exploit is shared for download at github.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 6 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 105627 (GLSA-201801-01 : Binutils: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 8 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (42201), Tenable (105627) and SecurityFocus (BID 99113†). The entries VDB-98344, VDB-98345, VDB-98370 and VDB-98371 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
