Detailsinfo

A vulnerability classified as critical was found in GNU binutils 2.28 (Programming Tool Software). Affected by this vulnerability is the function ieee_archive_p of the file bfd/ieee.c of the component libbfd. 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. The summary by CVE is:

The ieee_archive_p function in bfd/ieee.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, might 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. NOTE: this may be related to a compiler bug.

The bug was discovered 06/13/2017. The weakness was published 06/19/2017 by Alex as Bug 21581 as confirmed bug report (Bugzilla). It is possible to read the advisory at sourceware.org. This vulnerability is known as CVE-2017-9747 since 06/18/2017. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details and also a public exploit are known.

A public exploit has been developed by Alexandre Adamski and been published immediately after the advisory. It is possible to download the exploit 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 105225 (openSUSE Security Update : binutils (openSUSE-2017-1330)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 171830 (OpenSUSE Security Update for binutils (openSUSE-SU-2018:3223-1)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 6 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (42200), Tenable (105225) and SecurityFocus (BID 99114†). Similar entries are available at VDB-98231, VDB-98373, VDB-99063 and VDB-99064. Be aware that VulDB is the high quality source for vulnerability data.
