Description Adam Mariš 2017-08-21 08:43:37 EDT

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.

Comment 2 Pedro Yóssis Silva Barbosa 2017-09-22 07:09:50 EDT

Marked binutils in RHEL 5, 6, 7 and devtools 4, 6 and 7, as not affected.
Red Hat does not ship binutils compiled with the --enable-targets=all configuration. Therefore, Product Security Team was not able to reproduce the issue.
