    descriptionUse-after-free vulnerability in lighttpd before 1.4.33 allows remote attackers to cause a denial of service (segmentation fault and crash) via unspecified vectors that trigger FAMMonitorDirectory failures. 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. lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached.

    descriptionSeveral vulnerabilities have been discovered in the lighttpd web server. It was discovered that SSL connections with client certificates stopped working after the DSA-2795-1 update of lighttpd. An upstream patch has now been applied that provides an appropriate identifier for client certificate verification. - CVE-2013-4508 It was discovered that lighttpd uses weak ssl ciphers when SNI (Server Name Indication) is enabled. This issue was solved by ensuring that stronger ssl ciphers are used when SNI is selected. - CVE-2013-4559 The clang static analyzer was used to discover privilege escalation issues due to missing checks around lighttpd

    descriptionAccording to its banner, the version of lighttpd running on the remote host is prior to 1.4.34. It is, therefore, affected by the following vulnerabilities : - When Server Name Indication (SNI) is enabled, a flaw exists that could cause the application to use all available SSL ciphers, including weak ciphers. Remote attackers could potentially hijack sessions or obtain sensitive information by sniffing the network. Note only versions 1.4.24 to 1.4.33 are affected. (CVE-2013-4508) - A flaw exists in the clang static analyzer because it fails to perform checks around setuid (1), setgid (2), and setgroups (3) calls. This could allow a remote attacker to gain elevated privileges. (CVE-2013-4559) - A use-after-free error exists in the clang static analyzer, when the FAM stat cache engine is enabled. This could allow remote attackers to dereference already freed memory and crash the program. (CVE-2013-4560) Note that Nessus has not tested for these issues but has instead relied only on the application

    descriptionUpdated 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).
