Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
