Severity:	normal
Title:	lighttpd: Multiple vulnerabilities
Date:	03/05/2008
Bugs:	#211230, #211956
ID:	200803-10

Synopsis

Multiple vulnerabilities have been discovered in lighttpd.

Background

lighttpd is a lightweight high-performance web server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-servers/lighttpd	< 1.4.18-r2	>= 1.4.18-r2	All supported architectures

Description

lighttpd contains a calculation error when allocating the global file descriptor array (CVE-2008-0983). Furthermore, it sends the source of a CGI script instead of returning a 500 error (Internal Server Error) when the fork() system call fails (CVE-2008-1111).

Impact

A remote attacker could exploit these vulnerabilities to cause a Denial of Service or gain the source of a CGI script.

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-1.4.18-r2"
