Severity: Normal Title: Lighttpd: Two Denials of Service Date: May 07, 2007 Bugs: #174043 ID: 200705-07

Synopsis ========
Two vulnerabilities have been discovered in Lighttpd, each allowing for a Denial of Service.
Background ==========
Lighttpd is a lightweight HTTP web server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.14 >= 1.4.14
Description ===========
Robert Jakabosky discovered an infinite loop triggered by a connection abort when Lighttpd processes carriage return and line feed sequences. Marcus Rueckert discovered a NULL pointer dereference when a server running Lighttpd tries to access a file with a mtime of 0.
Impact ======
A remote attacker could upload a specially crafted file to the server or send a specially crafted request and then abort the connection, possibly resulting in a crash or a Denial of Service by CPU consumption.
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-1.4.14"
