A vulnerability was found in GNU binutils 2.28 (Programming Tool Software). It has been rated as critical. Affected by this issue is the function process_otr
of the file bfd/versados.c of the component libbfd. The manipulation as part of a Binary File leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:
The process_otr function in bfd/versados.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, does not validate a certain offset, which 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.
The bug was discovered 06/13/2017. The weakness was disclosed 06/19/2017 by Alex as Bug 21591 as not defined bug report (Bugzilla). The advisory is available at sourceware.org. This vulnerability is handled as CVE-2017-9754 since 06/18/2017. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit.
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.
