Title: GNU Binutils堆缓冲区溢出漏洞（CNVD-2019-22404）

Description:

GNU Binutils是一组用于创建和管理二进制程序、对象文件、库、配置文件数据及程序集源代码的编程工具。

GNU Binutils 2.32中使用的二进制文件描述符(BFD)库中的bfd.c中的_bfd_doprnt存在堆缓冲区溢出漏洞。该漏洞源于elfcode.h中的elf_object_p未能正确处理SHT_GROUP类型的e_shstrndx部分（忽略了尾随的0字符）。攻击者可通过特制ELF输入利用该漏洞导致拒绝服务。

Summary

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.
