Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

A vulnerability in ZNC allows for privilege escalation.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

ZNC is an advanced IRC bouncer.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------
     Package      /  Vulnerable  /                          Unaffected
    -------------------------------------------------------------------
  1  net-irc/znc       < 0.066                                >=3D 0.066


Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

cnu discovered multiple CRLF injection vulnerabilities in ZNC's
webadmin module.

Impact
=3D=3D=3D=3D=3D=3D

A remote authenticated attacker could modify the znc.conf configuration
file and gain privileges via newline characters in e.g. the QuitMessage
field, and possibly execute arbitrary code.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All ZNC users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dnet-irc/znc-0.066"
