Security Team Weekly Summary: December 7, 2017

The Security Team weekly reports are intended to be very short summaries of the Security Team’s weekly activities.

If you would like to reach the Security Team, you can find us at the #ubuntu-hardened channel on FreeNode. Alternatively, you can mail the Ubuntu Hardened mailing list at: ubuntu-hardened@lists.ubuntu.com

Due to the holiday last week, there was no weekly report, so this report covers the previous two weeks. During the last two weeks, the Ubuntu Security team:

  • Triaged 379 public security vulnerability reports, retaining the 74 that applied to Ubuntu.
  • Published 32 Ubuntu Security Notices which fixed 70 security issues (CVEs) across 34 supported packages.
