CVE-2014-5139

TITLE

OpenSSL Denial of service vulnerability

DESCRIPTION

The ssl_set_client_disabled function in t1_lib.c in OpenSSL 1.0.1 before 1.0.1i allows remote SSL servers to 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. OpenSSL is prone to a local denial-of-service vulnerability. An attacker may exploit this issue to crash the application, resulting in denial-of-service conditions. OpenSSL 1.0.1 prior to 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. 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. Double Free when processing DTLS packets (CVE-2014-3505) ======================================================== 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. 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. 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. All applications linked to openssl need to be restarted. Alternatively, you may reboot your system. For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u12. For the testing distribution (jessie), these problems will be fixed soon. For the unstable distribution (sid), these problems have been fixed in version 1.0.1i-1. ============================================================================ Ubuntu Security Notice USN-2308-1 August 07, 2014 openssl vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: Several security issues were fixed in OpenSSL.
