lighttpd SSL error denial of service
|lighttpd-sslerror-dos (41545)||Medium Risk|
lighttpd is vulnerable to a denial of service, caused by an SSL error when the SSL support is enabled. By persuading a victim to connect or disconnect prior to a finished download, a remote attacker could exploit this vulnerability to cause all active SSL connections to close, resulting in a denial of service.
Denial of Service
Upgrade to the latest version of lighttpd (1.4.20 or later), available from the LIGHTTPD Web site. See References.

- CVE-2008-1531: The connection_state_machine function (connections.c) in lighttpd 1.4.19 and earlier, and 1.5.x before 1.5.0, allows remote attackers to cause a denial of service (active SSL connection loss) by triggering an SSL error, such as disconnecting before a download has finished, which causes all active SSL connections to be lost.
