Release Notes

cert-manager/cert-manager (cert-manager/cert-manager)

v1.12.4

Compare Source

v1.12.4 contains an important security fix that addresses CVE-2023-29409.

Changes since v1.12.3

• Fixes an issue where cert-manager would incorrectly reject two IP addresses as being unequal when they should hav
  e compared equal. This would be most noticeable when using an IPv6 address which doesn't match how Go's net.IP.Str ing() function would have printed that address. (#​6297, @​SgtCoDFish)
• Use Go 1.20.7 to fix a security issue in Go's crypto/tls library. (#​6318, @​maelvls)
