GHSA-6cp7-g972-w9m9
Use of a Key Past its Expiration Date and Insufficient Session Expiration in Maddy Mail Server
Quick fix
GHSA-6cp7-g972-w9m9 — github.com/foxcpp/maddy: upgrade to the fixed version with the command below.
go get github.com/foxcpp/maddy@v0.5.4Details
### Impact
Any configuration on any maddy version <0.5.4 using auth.pam is affected.
No password expiry or account expiry checking is done when authenticating using PAM.
### Patches
Patch is available as part of the 0.5.4 release.
### Workarounds
If /etc/shadow authentication is used, it is possible to replace auth.pam with auth.shadow which is not affected.
It is possible to blacklist expired accounts via existing filtering mechanisms (e.g. auth_map to invalid accounts in storage.imapsql).
