Synopsis
========
Multiple vulnerabilities have been found in Gentoo's JabberD 2.x
ebuild, the worst of which allows local attackers to escalate
privileges.
Background
==========
JabberD 2.x is an open source Jabber server written in C.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/jabberd2 <= 2.6.1 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
Multiple vulnerabilities have been discovered in Gentoo's JabberD 2.x
ebuild. Please review the referenced CVE identifiers for details.
Impact
======
An attacker could possibly escalate privileges by owning system
binaries in trusted locations, cause a Denial of Service condition by
manipulating the PID file from jabberd2 services, bypass security via
SASL ANONYMOUS connections or have other unspecified impacts.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
Gentoo has discontinued support for JabberD 2.x and recommends that
users unmerge the package:
# emerge --unmerge "net-im/jabberd2"
As an alternative, users may want to upgrade their systems to use
net-im/prosody instead of net-im/jabberd2.
