CVE-2019-12972

Date: June 26, 2019

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.

Language: C
