AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions binutils versions prior to 2.34

Description The issue is related to a flaw in the bfd pef parse function stubs function of bfd/pef.c in binutils, which could allow an attacker to cause a NULL pointer dereference by submitting a crafted file to be processed by objdump. This flaw poses the greatest threat to application availability.

Recommendations For versions prior to 2.34, update to version 2.34 or later to resolve the issue. As a temporary workaround, consider restricting the use of the bfd pef parse function stubs function until a patch is available. Avoid using objdump to process crafted files until the issue is resolved.
