Debian Security Advisory DSA 2795-2 (lighttpd - several vulnerabilities)

Published: 2013-11-16 23:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:H/Au:N/C:C/I:C/A:C

Affected Versions:
lighttpd on Debian Linux

Recommendations:
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. 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. For the testing (jessie) and unstable (sid) distributions, the regression problem will be fixed soon. We recommend that you upgrade your lighttpd Linux Distribution Packages.

Summary:
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.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
