CVE-2025-69644
Description
A flaw was found in binutils. A local attacker can exploit a logic flaw in the handling of DWARF (Debugging With Attributed Record Formats) location list headers within the objdump utility. By supplying a crafted binary with malformed debug information, the attacker can cause objdump to enter an unbounded loop, leading to excessive resource consumption and a Denial of Service (DoS).
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
