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=1727276,1765139 # 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 Carl, could you please have a look? We will not be fixing this one in Fedora. I looked into this a bit, and I see that it's not exploitable on a fully patched RHEL/CentOS 7 due to glibc already being patched for CVE-2016-10739. https://access.redhat.com/security/cve/cve-2019-18348 I'm not opposed to patching this in the EPEL 6 package, but I'm not sure where to start. I found this upstream bug, but it doesn't reference a commit or pull request fixing the flaw in other branches. https://bugs.python.org/issue38576 Got any pointers of where to start writing a patch to fix this? There is no upstream fix for this issue yet, as it is mainly visible on systems where CVE-2016-10739 is not already patched (e.g. some versions of RHEL 7 and maybe some other distros that ship an old glibc version). |
