Amazon Linux 2027 Preview Security Advisory: ALAS2027-2026-312
Advisory Released Date: 2026-11-09
Advisory Updated Date: 2026-11-10
Severity:
Medium
Issue Overview:
Package updates are available for Amazon Linux 2027 that fix the following vulnerabilities:
CVE-2026-82247:
gitoxide's gix-url crate (<= 0.32.0, fixed in 0.37.1) uses a hand-rolled URL parser that does not treat '?' or '#' as terminating the authority component, contrary to RFC 3986. As a consequence, gix-transport's HTTP redirect identity guard (can_reuse_identity) compares the wrong host and fails open. An attacker controlling a redirect response can craft a Location header of the form <attacker-authority>?@<original-authority> so that gitoxide sends the caller's HTTP Basic Authorization credentials to an unintended host. gix-transport is affected in versions <= 0.49.0 (fixed in 0.58.1).
Affected Packages:
rust-cargo-c
Issue Correction:
Run dnf update rust-cargo-c --releasever 2027.0.20261109 or dnf update --advisory ALAS2027-2026-312 --releasever 2027.0.20261109 to update your system.
