| Security researchers at Google, namely Pedro Gallegos, Simon Scannell, and Jasiel Spelman, identified vulnerabilities in both the rsync server and client. The server vulnerabilities ([CVE-2024-12084](https://access.redhat.com/security/cve/CVE-2024-12084) and [CVE-2024-12085](https://access.redhat.com/security/cve/CVE-2024-12085)) can lead to remote code execution (RCE). On the client side, vulnerabilities allow a malicious server to read arbitrary files ([CVE-2024-12086](https://access.redhat.com/security/cve/CVE-2024-12086)), create unsafe symlinks ([CVE-2024-12087](https://access.redhat.com/security/cve/CVE-2024-12087)), and, under certain conditions, overwrite arbitrary files ([CVE-2024-12088](https://access.redhat.com/security/cve/CVE-2024-12088)). Additionally, during the coordinated response to these issues, Aleksei Gorban reported a sixth vulnerability ([CVE-2024-12747](https://access.redhat.com/security/cve/CVE-2024-12747)) related to how the rsync server manages symlinks. | ||

| # Impact and Mitigation: | ||
|
|
||
| ## AlmaLinx rsync Backport Packages | ||
| On January 14, 2025 we released updates for our [backported rsync RPMs](https://wiki.almalinux.org/Mirrors.html) - mainly tailored to mirror owners. rsync from this backport repo was at version 3.3.0, which was vulnerable to all 6 CVEs. rsync 3.4.0 was released to address them all, and subsequently 3.4.1 to address regressions discovered in 3.4.0. We updated the repo to 3.4.0 and subsequently 3.4.1. | ||

| ## AlmaLinux Kitten 10 | ||
| On January 14, 2025 we released updated package for AlmaLinux Kitten 10 addressing all six vulnerabilities. At the time of this posting, Red Hat has not patched CentOS Stream 9 or CentOS Stream 10. If Red Hat chooses to only patch some of the vulnerabilities we will continue to carry patches for all of them within AlmaLinux Kitten 10 - a potential deviation from Red Hat. | ||

| ## AlmaLinux 8 & AlmaLinux 9 | ||
| AlmaLinux 8 and AlmaLinux 9 are vulnerable only to 5 of the 6 CVEs - CVE-2024-12085, CVE-2024-12086, CVE-2024-12087, CVE-2024-12088, and CVE-2024-12747. On January 14, 2025 we prepared packages for AlmaLinux 8 and AlmaLinux 9 with plans to release them on January 15, 2025. Red Hat released updates on January 15, 2025 addressing only CVE-2024-12085 which we promptly released for [AlmaLinux 8](https://errata.almalinux.org/8/ALSA-2025-0325.html) and [AlmaLinux 9](https://errata.almalinux.org/9/ALSA-2025-0324.html) as well. Our builds that patch all five vulnerabilities have not been released as of this posting. | ||
|
|
||
| We have patched builds to address all five CVEs but have not released them as of yet. ALESCo is working to decide if we will release these patched builds and carry the patches moving forward if Red Hat does not also patch them. This would be a deviation from Red Hat. If these patches are important to you and your rsync use-cases please [let ALESCo know](https://chat.almalinux.org/almalinux/channels/alesco)! | ||

I'm not sure I like this title. Is this preferential or a blocker?
Not set on mine, just not sure I like what you posed :) It seems too basic IMO I guess

A title update is a blocker, but I'm okay with something else. Yours is too long and technical (I know, technical blog and all, but it still needs to be MUCH shorter and simpler).

How about "Rsync vulnerabilities - patching status" ?
