CVE-2018-10535 (opens in a new tab)How to fix?
Upgrade Ubuntu:18.04 binutils to version 2.30-21ubuntu1~18.04.3 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 Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab entry with a "SECTION" type that has a "0" value, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy.
