March 29, 2026
Update rust-astral-tokio-tar to 0.6.0, fixing CVE-2026-32766
Summary
A Rust implementation of an async TAR file reader and writer. This
library does not currently handle compression, but it is abstract over
all I/O readers and writers. Additionally, great lengths are taken to
ensure that the entire contents are never required to be entirely
resident in memory all at once.
