Gentoo Linux Security Advisory
Title: Lighttpd: Two Denials of Service (GLSA 200705-07)
Severity: normal
Exploitable: remote
Date: May 07, 2007
Bug(s): #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: www-servers/lighttpd
Vulnerable: < 1.4.14
Unaffected: >= 1.4.14
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.14" |
