The podcast discusses the recent SSH vulnerability and its potential consequences for sensitive networks. They also highlight a privacy issue with cloud-connected security cameras and the lack of end-to-end encryption. Additionally, they address listener questions about ZFS encryption and discuss a bug related to encrypted streams in ZFS.
SSH vulnerabilities in OpenSSH can weaken security and caution is advised for users of third-party SSH apps.
The privacy breach with ubiquity security cameras highlights the risks of relying on cloud-based solutions for security camera footage storage.
Deep dives
Terrapin SSH Vulnerabilities
The podcast episode discusses a series of three vulnerabilities known as Terrapin that affect SSH. The first vulnerability allows an attacker to interfere during the SSH setup process and potentially disable newer features in OpenSSH. The second and third vulnerabilities specifically impact async SSH, a Python SSH server. While most users of Linux or BSD machines that utilize SSH are not at high risk, caution is advised for those who use third-party SSH apps on Android or Windows, such as Juice SSH or PuTTY. However, the vulnerabilities are being actively patched in OpenSSH, and ensuring both the client and server are updated should help mitigate the risks.
Ubiquity Security Camera Privacy Breach
The podcast episode discusses a recent privacy breach involving ubiquity security cameras where private video footage was mistakenly broadcasted to other users' accounts. This breach raises concerns regarding users' privacy and the potential exposure of sensitive content captured by these cameras. The incident highlights the risks associated with relying on third-party cloud services for security camera footage storage. The podcast raises questions concerning the use of end-to-end encryption and points out that many cheaper IoT-grade cameras offer this feature, questioning why ubiquity didn't prioritize implementing it. Users are advised to reconsider relying solely on cloud-based solutions for security camera footage to ensure better control over their privacy and sensitive information.
ZFS Native Encryption and Send/Receive
A listener queries the reliability of ZFS native encryption and its compatibility with send/receive functionality. The podcast hosts explain that while there have been reports of bugs related to ZFS encryption and send/receive, these issues appear to affect a relatively small subset of users, primarily with using the Raw Send option. The bug, which occasionally causes replication to fail due to ZFS returning a false space error, has not resulted in data loss. The hosts stress the importance of reporting bugs with detailed information and following up with developers to aid in identifying and resolving these issues. They suggest maintaining additional backup measures apart from relying solely on ZFS native encryption and Raw Send for important data to ensure redundancy and data protection.
Syncoid Snapshots and Sanoid Management
A listener seeks clarification on the usage of Syncoid and Sanoid for managing ZFS snapshots. The hosts explain that Syncoid snapshots are independent of Sanoid and are created and managed solely by Syncoid itself. Syncoid automatically takes a snapshot prior to initiating replication and maintains only the latest snapshot at the target location. Additional snapshots are the responsibility of Sanoid, which should be configured to create and manage multiple snapshots according to specific retention policies. It is emphasized that multiple Syncoid snapshots are not necessary, as they primarily serve the purpose of ensuring synchronization and data integrity between source and target locations.
What you need to know about the recent SSH vulnerability, yet another privacy issue with cloud-connected security cameras, why it’s difficult to get to the bottom of an obscure ZFS encryption bug, and more.
