Detailsinfo

A vulnerability was found in GNU binutils 2.29.1 (Programming Tool Software). It has been rated as critical. This issue affects the function pe_bfd_read_buildid of the file peicode.h of the component libbfd. The manipulation as part of a File Descriptor leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The pe_bfd_read_buildid function in peicode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate size and offset values in the data dictionary, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted PE file.

The bug was discovered 11/01/2017. The weakness was shared 11/15/2017 as Bug 22373 as confirmed bug report (Bugzilla). It is possible to read the advisory at sourceware.org. The identification of this vulnerability is CVE-2017-16832 since 11/15/2017. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 14 days. During that time the estimated underground price was around $0-$5k.
