CVE-2018-10534 (opens in a new tab)How to fix?
Upgrade Debian:13 binutils to version 2.30.90.20180627-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
The _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, processes a negative Data Directory size with an unbounded loop that increases the value of (external_IMAGE_DEBUG_DIRECTORY) *edd so that the address exceeds its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c.
