A vulnerability, which was classified as problematic, has been found in GNU binutils 2.31 (Programming Tool Software). Affected by this issue is the function d_name/d_encoding/d_local_name of the file cp-demangle.c of the component GNU libiberty. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions d_name(), d_encoding(), and d_local_name() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm.

The bug was discovered 10/22/2018. The weakness was published 10/28/2018 (Website). The advisory is shared for download at gcc.gnu.org. This vulnerability is handled as CVE-2018-18700 since 10/27/2018. The attack may be launched remotely. No form of authentication is required for exploitation.
