Upstream patch: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=28e817cc440bce73691c03e01860089a0954a837
Function readelf.c:process_archive() uses filedata->file_name when printing errors, however until the file_name field is not properly initialized, it should not be accessed, otherwise it would access memory that is freed at the previous iteration.
The flaw was introduced with commit https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=dda8d76d0dd2b07df769f6cae20aff483468b342, thus RHEL 5, 6, 7 and Red Hat Developer Toolset 7 are not affected by this flaw.
Statement: This issue did not affect the versions of binutils as shipped with Red Hat Enterprise Linux 5, 6, and 7 as they did not include the vulnerable code, which was introduced in a newer version of the package.
