Summary

A heap buffer overflow exists in binutils in bfd/pef.c when a crafted PEF file is parsed by objdump, leading to an out-of-bounds read. The flaw affects binutils versions prior to 2.34.

Risk Assessment

An attacker can supply a malicious PEF file to crash objdump, impacting application availability. This is especially risky in environments that automatically process untrusted binaries.

Recommendation

Upgrade binutils to version 2.34 or later. Avoid running objdump on files from untrusted sources.
