Descriptions
slapd/connection.c in 389 Directory Server (formerly Fedora Directory Server) 1.3.4.x before 1.3.4.7 allows remote attackers to cause a denial of service (infinite loop and connection blocking) by leveraging an abnormally closed connection.
slapd/connection.c en 389 Directory Server (anteriormente Fedora Directory Server) 1.3.4.x en versiones anteriores a 1.3.4.7 permite a atacantes remotos causar una denegación de servicio (bucle infinito y bloqueo de conexion) aprovechándose de una conexión cerrada de manera anómala.
An infinite-loop vulnerability was discovered in the 389 directory server, where the server failed to correctly handle unexpectedly closed client connections. A remote attacker able to connect to the server could use this flaw to make the directory server consume an excessive amount of CPU and stop accepting connections (denial of service).
