FreeBSD : OpenSSL -- multiple vulnerabilities (8aff07eb-1dbd-11e4-b6ba-3c970e169bc2)

high Nessus Plugin ID 77036
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote FreeBSD host is missing one or more security-related updates.


The OpenSSL Project reports :

A flaw in OBJ_obj2txt may cause pretty printing functions such as X509_name_oneline, X509_name_print_ex et al. to leak some information from the stack. [CVE-2014-3508]

The issue affects OpenSSL clients and allows a malicious server to crash the client with a NULL pointer dereference (read) by specifying an SRP ciphersuite even though it was not properly negotiated with the client. [CVE-2014-5139]

If a multithreaded client connects to a malicious server using a resumed session and the server sends an ec point format extension it could write up to 255 bytes to freed memory. [CVE-2014-3509]

An attacker can force an error condition which causes openssl to crash whilst processing DTLS packets due to memory being freed twice. This can be exploited through a Denial of Service attack. [CVE-2014-3505]

An attacker can force openssl to consume large amounts of memory whilst processing DTLS handshake messages. This can be exploited through a Denial of Service attack. [CVE-2014-3506]

By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. [CVE-2014-3507]

OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to a denial of service attack. A malicious server can crash the client with a NULL pointer dereference (read) by specifying an anonymous (EC)DH ciphersuite and sending carefully crafted handshake messages. [CVE-2014-3510]

A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher protocol version, by modifying the client's TLS records. [CVE-2014-3511]

A malicious client or server can send invalid SRP parameters and overrun an internal buffer. Only applications which are explicitly set up for SRP use are affected. [CVE-2014-3512]
