This will ensure that all associated bugs get updated when new packages are pushed to stable. ===== # bugfix, security, enhancement, newpackage (required) type=security # low, medium, high, urgent (required) severity=medium # testing, stable request=testing # Bug numbers: 1234,9876 bugs=1683150,1683153 # Description of your update notes=Security fix for [PUT CVEs HERE] # Enable request automation based on the stable/unstable karma thresholds autokarma=True stable_karma=3 unstable_karma=-3 # Automatically close bugs when this marked as stable close_bugs=True # Suggest that users restart after update suggest_reboot=False ====== Additionally, you may opt to use the bodhi web interface to submit updates: https://bodhi.fedoraproject.org/updates/new Note: Per upstream guidelines, this is not a security bug, despite the CVE assignment. The regular expression compiler in glibc is only supposed to be exposed to trusted content, so this is not a security vulnerability: “resource exhaustion issues which can be triggered only with crafted patterns (either during compilation or execution) are not treated as security bugs” <https://sourceware.org/glibc/wiki/Security%20Exceptions> |
