Detailsinfo

A vulnerability, which was classified as critical, was found in GNU binutils 2.28 (Programming Tool Software). This affects the function get_build_id of the file opncls.c of the component libbfd. The manipulation as part of a File Descriptor 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 get_build_id function in opncls.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file in which a certain size field is larger than a corresponding data field, as demonstrated by mishandling within the objdump program.

The bug was discovered 06/23/2017. The weakness was disclosed 06/26/2017 (Website). The advisory is shared at sourceware.org. This vulnerability is uniquely identified as CVE-2017-9955 since 06/26/2017. 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 are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 3 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 170587 (OpenSUSE Security Update for binutils (openSUSE-SU-2017:3199-1)).

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 Tenable (105225) and SecurityFocus (BID 99573†). The entries VDB-98231, VDB-98373, VDB-99063 and VDB-99064 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
