Doc Text:
A flaw was found in binutils, specifically in the `objdump` utility. A local attacker can exploit this vulnerability by providing a specially crafted binary file containing malformed DWARF (Debugging With Attributed Record Formats) debug information. This can lead to a logic error during the processing of DWARF compilation units, causing the `objdump` utility to crash and resulting in a denial of service.

Description OSIDB Bzimport 2026-03-06 18:01:28 UTC
Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug information. A logic error in the handling of DWARF compilation units can result in an invalid offset_size value being used inside byte_get_little_endian, leading to an abort (SIGABRT). The issue was observed in binutils 2.44. A local attacker can trigger the crash by supplying a malicious input file.
