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 systems
using this compression library; therefore, it's strongly recommended to use a
version later than 5.6.0 if possible to mitigate this risk.
Key points about the difference:
Vulnerability:
The main concern with older versions like 5.4.5 is the potential presence of a
malicious "backdoor" discovered in the 5.6 series, which could enable
unauthorized access to systems.
Security updates:
Version 5.6.4 is likely to include security patches addressing the "backdoor"
vulnerability, making it a more secure option.
Functionality changes:
While security is the primary concern, there could also be minor functional
updates or bug fixes introduced between versions 5.4.5 and 5.6.4.
