A Denial of Service vulnerability was discovered in EnergyMech that is easily exploitable via IRC.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-irc/emech | * | < 3.0.2 | >= 3.0.2 |
EnergyMech is an IRC bot programmed in C.
A bug in EnergyMech fails to handle empty CTCP NOTICEs correctly, and will cause a crash from a segmentation fault.
By sending an empty CTCP NOTICE, a remote attacker could exploit this vulnerability to cause a Denial of Service.
There is no known workaround at this time.
All EnergyMech users should update to the latest stable version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/emech-3.0.2"
