An issue was discovered in WeeChat before 2.7.1 (0.3.4 to 2.7 are affected). When a new IRC message 005 is received with longer nick prefixes, a buffer overflow and possibly a crash can happen when a new mode is set for a nick.
Se detectó un problema en WeeChat versiones anteriores a 2.7.1 (versiones 0.3.4 hasta 2.7 están afectadas). Cuando se recibe un nuevo mensaje 005 IRC con prefijos nick más largos, un desbordamiento del búfer y posiblemente un bloqueo puede presentarse cuando se ajusta un nuevo modo para un nick.
Multiple vulnerabilities have been found in WeeChat, the worst of which could allow remote attackers to cause a Denial of Service condition. Versions less than 2.7.1 are affected.
