Subj : A backdoor in xz To : All From : LWN.net Date : Fri Mar 29 2024 17:45:05 A backdoor in xz Date: Fri, 29 Mar 2024 17:33:57 +0000 Description: Andres Freund has posted a detailed investigation into a backdoor that was shipped with versions 5.6.0 and 5.6.1 of the xz compression utility. It appears that the malicious code may be aimed at allowing SSH authentication to be bypassed. I have not yet analyzed precisely what is being checked for in the injected code, to allow unauthorized access. Since this is running in a pre-authentication context, it seems likely to allow some form of access or other form of remote code execution. The affected versions are not yet widely shipped, but checking systems for the bad version would be a good idea. ====================================================================== Link to news story: https://lwn.net/Articles/967180/ --- Mystic BBS v1.12 A47 (Linux/64) * Origin: tqwNet UK HUB @ hub.uk.erb.pw (1337:1/100) .
