CVE-2014-3512

Multiple buffer overflows in crypto/srp/srp_lib.c in the SRP implementation in OpenSSL 1.0.1 before 1.0.1i allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid SRP (1) g, (2) A, or (3) B parameter.

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. Applications may be affected if they echo pretty printing output to the attacker. OpenSSL SSL/TLS clients and servers themselves are not affected (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. This can be exploited through a Denial of Service attack (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).
