Package        : lighttpd
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2013-4508 CVE-2013-4559 CVE-2013-4560
Debian Bug     : 729453

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.
