This release contains an upgrade to astral-tokio-tar, which addresses
a vulnerability in tar extraction on malformed archives with
mismatching size information between the ustar header and PAX
extensions. While the astral-tokio-tar advisory has been graded as
"high" due its potential broader impact, the specific impact to uv is
low due to a lack of novel attacker capability. Specifically, uv only
processes tar archives from source distributions, which already
possess the capability for full arbitrary code execution by design,
meaning that an attacker gains no additional capabilities through
astral-tokio-tar.
Regardless, we take the hypothetical risk of parser differentials very
seriously. Out of an abundance of caution, we have assigned this
upgrade an advisory:
