Security update for ignition

This update for ignition fixes the following issues

  • CVE-2026-39821: golang.org/x/net/idna: failure to reject ASCII-only Punycode-encoded labels allows for validation bypass and privilege escalation (bsc#1266606).
  • CVE-2026-56852: golang.org/x/text/unicode/norm: handling of input containing invalid UTF-8 bytes can lead to infinite loop (bsc#1272059).

Описание

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".
