Use the following template to for the 'fedpkg update' request to submit an update for this issue as it contains the top-level parent bug(s) as well as this tracking bug. 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=1977975,1977976 # 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 We are looking at at fixing this in F34 and F33, but we need backports to the upstream stable branches. We need to do the following:
- Backport 5adda61f62b77384718b4c0d8336ade8f2b4b35c from master to release/master/2.33 (post to libc-stable)
- Backport 5adda61f62b77384718b4c0d8336ade8f2b4b35c from master to release/master/2.32 (post to libc-stable)
- Sync release/master/2.33 to Fedora 34
- Sync release/master/2.32 to Fedora 33
- Bodhi update for F34
- Bodhi update for F33

wordexp: handle overflow in positional parameter number (bug 28011)
Use strtoul instead of atoi so that overflow can be detected.
