Detailsinfo

A vulnerability has been found in GNU Binutils up to 2.45 and classified as problematic. This vulnerability affects an unknown function of the component DWARF Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. CVE summarizes:

An issue was discovered in Binutils before 2.46. The objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed debug information. A logic flaw in the handling of DWARF location list headers can cause objdump to enter an unbounded loop and produce endless output until manually interrupted. This issue affects versions prior to the upstream fix and allows a local attacker to cause excessive resource consumption by supplying a malicious input file.

The advisory is available at sourceware.org. This vulnerability was named CVE-2025-69644 since 01/09/2026. The exploitation appears to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available.
