ZNC is an advanced IRC bouncer.
It was discovered that ZNC’s “Modules.cpp” allows remote authenticated non-admin users to escalate privileges.
A remote authenticated attacker could escalate privileges and subsequently execute arbitrary code or conduct a Denial of Service attack.
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-1.7.4_rc1"
OS | Version | Architecture | Package | Version | Filename |
---|---|---|---|---|---|
Gentoo | any | all | net-irc/znc | < 1.7.4_rc1 | UNKNOWN |
