SIG-Linux Topic: Recent XZ utils backdoor issue

Presented by Sharan Kalwani

During some routine testing a developer noticed odd behavior and upon further  investigation, found that the XZ Utils – which is used for compression/decompression – had some text files added as a binary which added a backdoor.

We will describe this in some detail and of course you don’t need to worry too much about it since it has been very quickly addressed. More fun details in the actual talk itself.
