Detailsinfo

A vulnerability was found in GNU binutils 2.29 (Programming Tool Software) and classified as problematic. This issue affects an unknown functionality of the file dwarf2.c of the component Incomplete Fix. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability.
