Amazon Linux 2 Security Advisory: ALAS2-2026-3818
Advisory Released Date: 2026-07-20
Advisory Updated Date: 2026-07-20
On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open("symlink/")' will open "symlink" even when "symlink" is a symbolic link pointing outside of the root. (CVE-2026-39822)
Handshakes which used Encrypted Client Hello could be de-anonymized by a passive network observer due to a disclosure of pre-shared key identities in the unencrypted client hello. (CVE-2026-42505)
