podman: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862)
podman: golang.org/x/text: Denial of Service via invalid UTF-8 input (CVE-2026-56852)
podman: net/mail: Denial of Service via pathological email address parsing (CVE-2026-42499)
podman: Quadlet install --replace non-truncating write retains removed host-access directives (CVE-2026-19730)

CVE-2026-56862 (GCVE-0-2026-56862)

Vulnerability from cvelistv5 – Published: 2026-08-13 21:58 – Updated: 2026-08-14 15:29

Title

Limit handshake messages we are willing to accept post-handshake in crypto/tls

Summary

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.

Severity

7.5 (High)
