AusCERT Week in Review for 8th June 2018 8 Jun 2018
AusCERT is back to business as usual after the conference, and so is the security ecosystem. This week delivered the usual suspects in vulnerability reporting - a Flash 0day, updates for both Firefox and Chrome, an Android update, and a slew of Cisco updates.
PageUp (a HR SaaS provider) has reported a breach of its systems, likely the largest in scope reported under the new mandatory breach notification laws. The company has as clients various Australian government departments, large Australian businesses across multiple sectors, and parts of the education sector. Clients such as Wesfarmers (Coles, Target, Kmart, amongst others), the Australian Red Cross, and Medibank have made statements that they have suspended access to the service pending further updates and assurances. Since the system is customisable, the data potentially exposed may vary by client. Australia Post has stated that it requested TFNs, bank and superannuation details, and driver licence numbers from successful candidates via the service. Though passwords were salted and hashed, users are recommended to change their passwords. No matter how heat-death-of-the-universe-scale your hashing algorithm's time complexity is, it's no match for "Password123".
Here's a summary (including excerpts) of some of the more interesting stories we've seen this week:

Adobe Patches Zero-Day Flash Flaw
Author: Brian Krebs
Excerpt: "Adobe has released an emergency update to address a critical security hole in its Flash Player browser plugin that is being actively exploited to deploy malicious software. If you've got Flash installed - and if you're using Google Chrome or a recent version of Microsoft Windows you do - it's time once again to make sure your copy of Flash is either patched, hobbled or removed."
Here are this week's noteworthy security bulletins:
1) ESB-2018.1706 - ALERT [Win][Linux][Mac] Adobe Flash Player: Multiple vulnerabilities
Another week, another Flash 0day.
2) ASB-2018.0126 - [Win][UNIX/Linux] Google Chrome: Multiple vulnerabilities
Google has patched an issue in Chrome where the CSP header was handled incorrectly. No technical details yet, but always keep your browser up to date.
3) ESB-2018.1664 - [Debian] Debian 7: Reduced security - Unknown/unspecified
It had a good run, but Debian 7 has reached End of Life. Jessie and Stretch are eagerly awaiting your upgrade.
4) ESB-2018.1702 - [Cisco] Multiple Cisco Products: Denial of service - Remote/unauthenticated
Turns out more than a few Cisco products have unbounded log file sizes which can be exploited to DoS the products by consuming all available disk space.
Stay safe, stay patched and have a good weekend!
