lighttpd SSL error denial of service
| lighttpd-sslerror-dos (41545) |  Low Risk |
Description:
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.
Platforms Affected:
- Debian, Debian Linux 4.0
- Gentoo, Linux
- lighttpd, lighttpd 1.4.19
Remedy:
Upgrade to the latest version of lighttpd (1.4.20 or later), available from the LIGHTTPD Web site. See References.
Consequences:
Denial of Service
