TITLE

OpenSSL of DTLS Implementation of d1_both.c Memory double free vulnerability

DESCRIPTION

Double free vulnerability in 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 (application crash) via crafted DTLS packets that trigger an error condition. Supplementary information : CWE Vulnerability type by CWE-415: Double Free ( Double release ) Has been identified. OpenSSL is prone to a denial-of-service vulnerability. An attacker can exploit this issue to crash the affected application, denying service to legitimate users. OpenSSL prior to 0.9.8zb, 1.0.0n, and 1.0.1i are vulnerable. OpenSSL Security Advisory [6 Aug 2014] ======================================== Information leak in pretty printing functions (CVE-2014-3508) ============================================================= 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. Thanks to Ivan Fratric (Google) for discovering this issue. This issue was reported to OpenSSL on 19th June 2014. The fix was developed by Emilia Käsper and Stephen Henson of the OpenSSL development team. Crash with SRP ciphersuite in Server Hello message (CVE-2014-5139) ================================================================== 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. OpenSSL 1.0.1 SSL/TLS client users should upgrade to 1.0.1i. Thanks to Joonas Kuorilehto and Riku Hietamäki (Codenomicon) for discovering and researching this issue. This issue was reported to OpenSSL on 2nd July 2014. The fix was developed by Stephen Henson of the OpenSSL core team. Race condition in ssl_parse_serverhello_tlsext (CVE-2014-3509) ============================================================== 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. OpenSSL 1.0.0 SSL/TLS client users should upgrade to 1.0.0n. OpenSSL 1.0.1 SSL/TLS client users should upgrade to 1.0.1i. Thanks to Gabor Tyukasz (LogMeIn Inc) for discovering and researching this issue. This issue was reported to OpenSSL on 8th July 2014. The fix was developed by Gabor Tyukasz. This can be exploited through a Denial of Service attack. Thanks to Adam Langley and Wan-Teh Chang (Google) for discovering and researching this issue. This issue was reported to OpenSSL on 6th June 2014. The fix was developed by Adam Langley. DTLS memory exhaustion (CVE-2014-3506) ====================================== 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. Thanks to Adam Langley (Google) for discovering and researching this issue. This issue was reported to OpenSSL on 6th June 2014. The fix was developed by Adam Langley. DTLS memory leak from zero-length fragments (CVE-2014-3507) =========================================================== By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. Thanks to Adam Langley (Google) for discovering and researching this issue. This issue was reported to OpenSSL on 6th June 2014. The fix was developed by Adam Langley. OpenSSL DTLS anonymous EC(DH) denial of service (CVE-2014-3510) =============================================================== 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. OpenSSL 0.9.8 DTLS client users should upgrade to 0.9.8zb OpenSSL 1.0.0 DTLS client users should upgrade to 1.0.0n. OpenSSL 1.0.1 DTLS client users should upgrade to 1.0.1i. Thanks to Felix Gröbert (Google) for discovering and researching this issue. This issue was reported to OpenSSL on 18th July 2014. The fix was developed by Emilia Käsper of the OpenSSL development team. OpenSSL TLS protocol downgrade attack (CVE-2014-3511) ===================================================== 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. OpenSSL 1.0.1 SSL/TLS server users should upgrade to 1.0.1i. Thanks to David Benjamin and Adam Langley (Google) for discovering and researching this issue. This issue was reported to OpenSSL on 21st July 2014. The fix was developed by David Benjamin. SRP buffer overrun (CVE-2014-3512) ================================== 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. Thanks to Sean Devlin and Watson Ladd (Cryptography Services, NCC Group) for discovering this issue. This issue was reported to OpenSSL on 31st July 2014. The fix was developed by Stephen Henson of the OpenSSL core team.

Detailed descriptions of the vulnerabilities can be found at: https://www.openssl.org/news/secadv_20140806.txt It's important that you upgrade the libssl1.0.0 package and not just the openssl package. Alternatively, you may reboot your system. For the testing distribution (jessie), these problems will be fixed soon. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security update Advisory ID: RHSA-2014:1054-01 Product: Red Hat Storage Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1054.html Issue date: 2014-08-14 CVE Names: CVE-2014-3505 CVE-2014-3506 CVE-2014-3507 CVE-2014-3508 CVE-2014-3509 CVE-2014-3510 CVE-2014-3511 ===================================================================== 1. Summary: Updated openssl packages that fix multiple security issues are now available for Red Hat Storage 2.1. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Storage Server 2.1 - x86_64 3. Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram Transport Layer Security (DTLS) protocols, as well as a full-strength, general purpose cryptography library. (CVE-2014-3509) It was discovered that the OBJ_obj2txt() function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. (CVE-2014-3508) A flaw was found in the way OpenSSL handled fragmented handshake packets. (CVE-2014-3511) Multiple flaws were discovered in the way OpenSSL handled DTLS packets. (CVE-2014-3505, CVE-2014-3506, CVE-2014-3507) A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman (DH) key exchange. (CVE-2014-3510) All OpenSSL users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted or the system rebooted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.
