CVE-2017-8393 Information

Description

The Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils 2.28 is vulnerable to a global buffer over-read error because of an assumption made by code that runs for objcopy and strip that SHT_REL/SHR_RELA sections are always named starting with a .rel/.rela prefix. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library such as objcopy and strip to crash.
