Fixed In Version: binutils-2.29-17.fc27, binutils-2.29.1-27.fc28
Doc Type: Bug Fix
Doc Text:
Cause: The BFD library's code for parsing ELF object files contained an assumption that the input was well formed. Consequence: The objdump program could be tricked into performing an illegal memory access and terminating if it was asked to examining a carefully corrupted input file. Fix: Add code to the BFD library to detect the corrupted input file and report it. Result: The objdump program successfully parses the corrupt binary and does not generate a segmentation fault.

This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora  'version' of '27'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 27 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Stale bug that does not affect any current releases, looks like the EOL closing script failed for some reason.
