Detailsinfo

A vulnerability, which was classified as problematic, was found in GNU binutils 2.29 (Programming Tool Software). Affected is the function scan_unit_for_symbols/parse_comp_unit of the file dwarf2.c of the component libbfd. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, does not validate the DW_AT_name data type, which allows remote attackers to cause a denial of service (bfd_hash_hash NULL pointer dereference, or out-of-bounds access, and application crash) via a crafted ELF file, related to scan_unit_for_symbols and parse_comp_unit.

The bug was discovered 10/04/2017. The weakness was presented 10/05/2017 (Website). The advisory is shared for download at blogs.gentoo.org. This vulnerability is traded as CVE-2017-15022 since 10/04/2017. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.
