CVE-2017-8395 Information

Description

The Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils 2.28 is vulnerable to an invalid write of size 8 because of missing a malloc() return-value check to see if memory had actually been allocated in the _bfd_generic_get_section_contents function. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library such as objcopy to crash.
