Detailsinfo

A vulnerability, which was classified as problematic, was found in GNU binutils 2.28 (Programming Tool Software). This affects some unknown processing of the file SHT_REL/SHR_RELA of the component BFD Library. The manipulation with an unknown input 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 availability. The summary by CVE is:

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to a global buffer over-read error because of an assumption made by code that runs for objcopy and strip, that SHT_REL/SHR_RELA sections are always named starting with a .rel/.rela prefix. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library, such as objcopy and strip, to crash.

The bug was discovered 05/01/2017. The weakness was published 05/01/2017 as Bug 21412 as not defined bug report (Bugzilla). The advisory is shared at sourceware.org. This vulnerability is uniquely identified as CVE-2017-8393 since 05/01/2017. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

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 8 months after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (105225). Similar entries are available at VDB-98231, VDB-98373, VDB-99063 and VDB-99064. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
