Summary
generated automatically from NVD dataF5 nginx versions 0.5.6 through 1.7.4 have a session handling flaw when multiple servers share the same ssl_session_cache or ssl_session_ticket_key. A cached SSL session can be reused for an unrelated context, so remote attackers with certain privileges could carry out "virtual host confusion" attacks. The weakness is classified as CWE-613, and Debian Linux is also listed as affected. The CVSS v2.0 score is 4.3 (MEDIUM), reflecting a network-based impact on integrity.
