Description D'juan McDonald (domhnall) 2019-06-27 17:23:49 UTC
(https://nvd.nist.gov/vuln/detail/CVE-2019-12972):

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.

@maintainer(s): 
fixed on Master via, commit:890f750a3b053532a4b839a2dd6243076de12031, milestone for 2.33 release.
