Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Cryptographic issues (CVE-ID: CVE-2013-6449)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client.
2) Cryptographic issues (CVE-ID: CVE-2013-6450)
The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.
The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c.
3) Input validation error (CVE-ID: CVE-2014-3505)
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) via crafted DTLS packets that trigger an error condition.
4) Resource management error (CVE-ID: CVE-2014-3506)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via crafted DTLS handshake messages that trigger memory allocations corresponding to large length values.
5) Memory leak (CVE-ID: CVE-2014-3507)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via zero-length DTLS fragments that trigger improper handling of the return value of a certain insert function. A remote attacker can perform a denial of service attack.
6) Race condition (CVE-ID: CVE-2014-3509)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Race condition in the ssl_parse_serverhello_tlsext function in t1_lib.c in OpenSSL 1.0.0 before 1.0.0n and 1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to cause a denial of service (memory overwrite and client application crash) or possibly have unspecified other impact by sending Elliptic Curve (EC) Supported Point Formats Extension data.
7) Input validation error (CVE-ID: CVE-2014-3510)
The vulnerability allows remote DTLS servers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and client application crash) via a crafted handshake message in conjunction with a (1) anonymous DH or (2) anonymous ECDH ciphersuite.
8) Input validation error (CVE-ID: CVE-2014-3511)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
9) Buffer overflow (CVE-ID: CVE-2014-3512)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
10) SRTP Memory Leak (CVE-ID: CVE-2014-3513)
The vulnerability allows a remote attacker to obtain potentially sensitive information and cause denial of service.The vulnerability exists due to a parsing error within DTLS SRTP extension in OpenSSL. A remote attacker can send a carefully crafted handshake message and free up to 64k of memory or cause denial of service conditions.
Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive data, stored in system memory, or cause the affected service to fail.
11) Session Ticket Memory Leak (CVE-ID: CVE-2014-3567)
The vulnerability allows a remote attacker to cause denial of service.The vulnerability exists due to an error when handling integrity of session tickets in OpenSSL. A remote attacker can send a large number of invalid session tickets and cause denial of service conditions.
Successful exploitation of the vulnerability may allow an attacker to perform a denial of service (DoS) attack.
12) Forced SSLv3 support (CVE-ID: CVE-2014-3568)
The vulnerability allows a remote attacker to force SSLv3 usage.When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. A remote attacker can force SSLv3 usage and perfom a variety of attacks against SSLv3 protocol
Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.
13) Input validation error (CVE-ID: CVE-2014-5139)
The vulnerability allows remote SSL servers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and client application crash) via a ServerHello message that includes an SRP ciphersuite without the required negotiation of that ciphersuite with the client.
