Synopsis
The remote Debian host is missing a security-related update.Description
Several 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'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.
Solution
Upgrade the lighttpd packages.For the oldstable distribution (squeeze), these problems have been fixed in version 1.4.28-2+squeeze1.5.
For the stable distribution (wheezy), these problems have been fixed in version 1.4.31-4+deb7u2.
