RUSTSEC-2021-0054 (CVE-2021-31919)

Vulnerability from osv_rustsec – Published: 2021-04-28 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

Archives may contain uninitialized memory

Details

rkyv is a serialization framework that writes struct-compatible memory to be stored or transmitted. During serialization, struct padding bytes and unused enum bytes may not be initialized. These bytes may be written to disk or sent over unsecured channels.

Severity

7.5 (High)
