Detailsinfo

A vulnerability, which was classified as critical, has been found in GNU binutils 2.30 (Programming Tool Software). This issue affects an unknown code block of the file dwarf2.c of the component libbfd. The manipulation with an unknown input 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:

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer underflow or overflow, and application crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm.

The bug was discovered 02/23/2018. The weakness was released 02/28/2018 (Website). It is possible to read the advisory at sourceware.org. The identification of this vulnerability is CVE-2018-7569 since 02/28/2018. 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 5 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 118337 (openSUSE Security Update : binutils (openSUSE-2018-1222)), which helps to determine the existence of the flaw in a target environment.
