Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2014-0221)
The vulnerability allows a remote attacker to perform a denial of service attack.The vulnerability exists due to an error when processing invalid DTLS handshake. A remote attacker can initiate SSL/TLS connection to the affected application and trigger denial of service conditions.
2) NULL pointer dereference (CVE-ID: CVE-2014-0198)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.The vulnerability exists due to a NULL pointer dereference error in the in the do_ssl3_write() function in OpenSSL. A remote attacker can send a specially crafted request to vulnerable application and trigger denial of service attack.
Successful exploitation of the vulnerability requires that SSL_MODE_RELEASE_BUFFERS is enabled.
3) Man-in-the-Middle attack (CVE-ID: CVE-2014-0224)
The vulnerability allows a remote attacker to decrypt encrypted connections.The vulnerability exists due to an error in OpenSSL. A remote attacker with ability to intercept network traffic can decrypt SSL connection and gain access to sensitive data.
4) Buffer overflow (CVE-ID: CVE-2014-0195)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The vulnerability exists due to a boundary error in OpenSSL when processing DTLS fragments to an OpenSSL DTLS client or server. A remote attacker can send a specially crafted request to vulnerable application and cause the server to crash or execute arbitrary code on the target system.
Successful exploitation of the vulnerability requires that server support DTLS.
5) Race condition (CVE-ID: CVE-2010-5298)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack or modify encrypted connection.The vulnerability exists due to a race condition in the ssl3_read_bytes() function in OpenSSL. A remote attacker can inject data across sessions or cause a denial of service
Successful exploitation of the vulnerability requires that SSL_MODE_RELEASE_BUFFERS is enabled.
6) Resource management error (CVE-ID: CVE-2014-3470)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.The vulnerability exists due to an error when processing ECDH ciphersuites in TLS clients. A remote attacker can send a specially crafted response to vulnerable OpenSSL client and cause the application to crash.
7) 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.
8) 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.
9) 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.
10) 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.
11) 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.
12) Information disclosure (CVE-ID: CVE-2014-3508)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The OBJ_obj2txt function in crypto/objects/obj_dat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of ' ' characters, which allows context-dependent attackers to obtain sensitive information from process stack memory by reading output from X509_name_oneline, X509_name_print_ex, and unspecified other functions.
13) 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.
14) Information disclosure (CVE-ID: CVE-2014-3566)
The vulnerability allows a remote attacker to perform MitM attack.The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.
Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.
Note: The vulnerability is known as POODLE.
