Malformed Binary File Crashes objdump with Unending Warnings
CVE-2025-69646
Summary
A bug in the objdump tool can cause it to freeze and run out of memory if it processes a specially crafted binary file. This can happen if an attacker provides a malicious file to objdump, leading to slow performance and potentially bringing the system to a standstill. To protect yourself, ensure you're running the latest version of objdump, and be cautious when processing unknown binary files.

Original description
Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug_rnglists data. A logic error in the handling of the debug_rnglists header can cause objdump to repeatedly print the same warning message and fail to terminate, resulting in an unbounded logging loop until the process is interrupted. The issue was observed in binutils 2.44. A local attacker can exploit this vulnerability by supplying a malicious input file, leading to excessive CPU and I/O usage and preventing completion of the objdump analysis.
