Updated lighttpd packages fix multiple security vulnerbilities

Publication date: 20 Nov 2013
Modification date: 20 Nov 2013
Type: security
Affected Mageia releases : 2 , 3
CVE: CVE-2013-4508 , CVE-2013-4559 , CVE-2013-4560

Description

Updated lighttpd packages fix security vulnerabilities:

lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which
makes it easier for remote attackers to hijack sessions by inserting packets
into the client-server data stream or obtain sensitive information by sniffing
the network (CVE-2013-4508).

In lighttpd before 1.4.34, if setuid() fails for any reason, for instance if an
environment limits the number of processes a user can have and the target uid
already is at the limit, lighttpd will run as root. A user who can run CGI
scripts could clone() often; in this case a lighttpd restart would end up with
lighttpd running as root, and the CGI scripts would run as root too
(CVE-2013-4559).

In lighttpd before 1.4.34, if "fam" is enabled and there are directories
reachable from configured doc roots and aliases on which FAMMonitorDirectory
fails, a remote client could trigger a DoS (CVE-2013-4560).
