Upgrade Debian:13 binutils to version 2.30-6 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 swap_std_reloc_in function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (aout_32_swap_std_reloc_out NULL pointer dereference and application crash) via a crafted ELF file, as demonstrated by objcopy.
