NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils-debuginfo package and not the binutils-debuginfo package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2 relevant fixed versions and status.
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.
