Ubuntu 24.04 Beta Postponed Due to Security Vulnerability

The anticipated release of Ubuntu 24.04 beta, scheduled for April 4, has been delayed due to the discovery of a critical security issue.

A backdoor was detected in recent versions of the xz compression library, potentially enabling attackers to compromise systems using SSH. This vulnerability, classified as 10 in CVSS 3 severity, is particularly concerning as it does not require physical access to the affected device.

While stable versions of Ubuntu remain unaffected by this flaw, those using daily builds with proposed updates enabled may be exposed. Canonical has advised extreme caution and recommends rebuilding all binary packages in the noble repos.

In response to this security concern, Canonical has decided to postpone the release of Ubuntu 24.04 beta to April 11. This additional time will allow for the rebuilding of every binary package and thorough testing to ensure the integrity of the release.

Impact on Users

Home users running stable versions of Ubuntu are not directly affected by this vulnerability. However, those using daily builds with proposed updates enabled should exercise caution and consider using their systems with restraint until the issue is resolved.

Steps Taken by Canonical

Canonical has promptly responded to the security issue by rebuilding all binary packages in the noble repos. This precautionary measure aims to mitigate any potential risks associated with the compromised xz library.

Conclusion

The postponement of Ubuntu 24.04 beta demonstrates Canonical's commitment to security and the importance of timely vulnerability mitigation. By delaying the release, Canonical ensures that the upcoming beta version is as secure as possible and minimizes any potential risks to users.
