Doc Text:
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).

Description OSIDB Bzimport 2026-03-06 18:01:34 UTC 
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.
