Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2013-4508)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network. Per: http://download.lighttpd.net/lighttpd/security/lighttpd_sa_2013_01.txt "All versions from 1.4.24 (first version supporting SNI) up to and including 1.4.33."
Remediation
Install update from vendor's website.
