Gentoo Linux Security Advisory

Title: Atheme IRC Services: Denial of Service (GLSA 201209-09)
Severity: normal
Exploitable: remote
Date: September 25, 2012
Bug(s): #409103
ID: 201209-09

Synopsis

A vulnerability has been found in Atheme which may lead to Denial
of Service or a bypass of security restrictions.


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.


Affected Packages

Package: net-irc/atheme-services
Vulnerable: < 6.0.10
Unaffected: >= 6.0.10
Architectures: All supported architectures


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