GLSA-200708-11 : Lighttpd: Multiple vulnerabilities
High Nessus Plugin ID 25917
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200708-11 (Lighttpd: Multiple vulnerabilities)
Stefan Esser discovered errors with evidence of memory corruption in the code parsing the headers. Several independent researchers also reported errors involving the handling of HTTP headers, the mod_auth and mod_scgi modules, and the limitation of active connections.
A remote attacker can trigger any of these vulnerabilities by sending malicious data to the server, which may lead to a crash or memory exhaustion, and potentially the execution of arbitrary code.
Additionally, access-deny settings can be evaded by appending a final / to a URL.
There is no known workaround at this time.
SolutionAll Lighttpd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/lighttpd-1.4.16'
