CVE-2020-35496

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 scan start address() 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 binutils 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 scan start address() function until a patch is available. Avoid using objdump to process untrusted or crafted files until the issue is resolved.
