We need to backport this upstream commit: commit d524fa6c35e675eedbd8fe6cdf4db0b49c658026 Author: H.J. Lu <hjl.tools> Date: Thu Nov 8 10:06:58 2018 -0800 Check multiple NT_GNU_PROPERTY_TYPE_0 notes [BZ #23509] Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. Since new linkers merge input .note.gnu.property sections into one output .note.gnu.property section, there is only one NT_GNU_PROPERTY_TYPE_0 note in one PT_NOTE segment with new linkers. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see multiple NT_GNU_PROPERTY_TYPE_0 notes in one PT_NOTE segment with older linkers. When an older linker is used to created the program on CET-enabled OS, the linker output has a single .note.gnu.property section with multiple NT_GNU_PROPERTY_TYPE_0 notes, some of which have IBT and SHSTK enable bits set even if the program isn't CET enabled. Such programs will crash on CET-enabled machines. This patch updates the note parser: 1. Skip note parsing if a NT_GNU_PROPERTY_TYPE_0 note has been processed. 2. Check multiple NT_GNU_PROPERTY_TYPE_0 notes.

glibc-2.28-20.fc29 has been pushed to the Fedora 29 stable repository. If problems still persist, please make note of it in this bug report.
This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '29'. 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 29 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.
