ID: 200903-02
A vulnerability in ZNC allows for privilege escalation.
ZNC is an advanced IRC bouncer.
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/znc < 0.066 >= 0.066
cnu discovered multiple CRLF injection vulnerabilities in ZNC's
webadmin module.
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.
There is no known workaround at this time.
All ZNC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/znc-0.066"
