AI Overview

The primary difference between xz versions 5.4.5 and 5.6.4 is that 5.6.4 is=
 a
newer version with potential security fixes and updates compared to 5.4.5,
particularly regarding a critical "backdoor" vulnerability discovered in the
5.6 series of xz utils, which could allow malicious actors to exploit syste=
ms
using this compression library; therefore, it's strongly recommended to use=
 a
version later than 5.6.0 if possible to mitigate this risk.=20
Key points about the difference:
