    Several vulnerabilities have been discovered in the lighttpd web server.
    
    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's setuid, setgid, and
        setgroups calls.  Those are now appropriately checked.
    
    CVE-2013-4560
    
        The clang static analyzer was used to discover a use-after-free issue
        when the FAM stat cache engine is enabled, which is now fixed.
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 1.4.28-2+squeeze1.4.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1.4.31-4+deb7u1.
    
    For the testing distribution (jessie), these problems will be fixed soon.
    
    For the unstable distribution (sid), these problems have been fixed in
    version lighttpd_1.4.33-1+nmu1.
    
    We recommend that you upgrade your lighttpd packages.
