Background

Atheme is a portable and secure set of open-source and modular IRC services. CertFP is certificate fingerprinting used to authenticate users to nicknames.

Description

The “myuser_delete()” function in account.c does not properly remove CertFP entries when deleting user accounts.

Impact

A remote authenticated attacker may be able to cause a Denial of Service condition or gain access to an Atheme IRC Services user account.

Workaround

There is no known workaround at this time.

Resolution

All Atheme users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/atheme-services-6.0.10"
