Didn't see this go by, but it looks hot enough to risk a repeat posting. >From a friend: It appears there's been a very serious effort to backdoor sshd on Linux via the xz compression/decompression system. https://www.openwall.com/lists/oss-security/2024/03/29/4 If you have anything running very recent Linux, it's worth investigating whether you're affected. IBM Red Hat says, if you're running Fedora 40 or Fedora Rawhide: > PLEASE IMMEDIATELY STOP USAGE OF ANY FEDORA > RAWHIDE INSTANCES for work or personal activity. The identity that did this got to the point of being not only an xz maintainer but a Linux kernel contributor, and contributed to a number of other Open Source projects as well over the course of years. The identity may have been compromised to do this, or may have been created to do this, and may have used other contributions to build rapport or to compromise more projects as well. I looked at the detection script available at the URL in the posting. It's harmless at worst (don't know yet if it can detect anything).
