CVE-2017-12448 Information

Description

The bfd_cache_close function in bfd/cache.c in the Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils 2.29 and earlier allows remote attackers to cause a heap use after free and possibly achieve code execution via a crafted nested archive file. This issue occurs because incorrect functions are called during an attempt to release memory. The issue can be addressed by better input validation in the bfd_generic_archive_p function in bfd/archive.c.
