lighttpd: Denial of Service — GLSA 201006-17

A processing error in lighttpd might result in a Denial of Service condition.

Affected Packages

www-servers/lighttpd on all architectures
Affected versions < 1.4.25-r1
Unaffected versions >= 1.4.25-r1

Background

lighttpd is a lightweight high-performance web server.

Description

Li Ming reported that lighttpd does not properly process packets that are sent overly slow.

Impact

A remote attacker might send specially crafted packets to a server running lighttpd, possibly resulting in a Denial of Service condition via host memory exhaustion.

Workaround

There is no known workaround at this time.

Resolution

All lighttpd users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.25-r1"
