MSRC_CVE-2025-69645

Vulnerability from csaf_microsoft - Published: 2026-03-02 00:00 - Updated: 2026-03-11 01:02
Summary
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.
