TITLE

OpenSSL of crypto/ec/ec_asn1.c of d2i_ECPrivateKey Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import. Supplementary information : CWE Vulnerability type by CWE-416: Use-after-free ( Use of freed memory ) Has been identified. OpenSSL is prone to remote memory-corruption vulnerability. Note: This issue was previously discussed in BID 73196 (OpenSSL Multiple Unspecified Security Vulnerabilities) but has been given its own record to better document it. Successfully exploiting this issue may allow an attacker to execute arbitrary code in the context of the application using the vulnerable library. Failed exploit attempts will result in denial-of-service conditions. The Common Vulnerabilities and Exposures project identifies the following issues: CVE-2015-0286 Stephen Henson discovered that the ASN1_TYPE_cmp() function can be crashed, resulting in denial of service. CVE-2015-0287 Emilia Kaesper discovered a memory corruption in ASN.1 parsing. CVE-2015-0292 It was discovered that missing input sanitising in base64 decoding might result in memory corruption. CVE-2015-0209 It was discovered that a malformed EC private key might result in memory corruption. CVE-2015-0288 It was discovered that missing input sanitising in the X509_to_X509_REQ() function might result in denial of service. For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u15. In this update the export ciphers are removed from the default cipher list.

OpenSSL Security Advisory [19 Mar 2015] ======================================= OpenSSL 1.0.2 ClientHello sigalgs DoS (CVE-2015-0291) ===================================================== Severity: High If a client connects to an OpenSSL 1.0.2 server and renegotiates with an invalid signature algorithms extension a NULL pointer dereference will occur. This can be exploited in a DoS attack against the server. This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 users should upgrade to 1.0.2a. This issue was was reported to OpenSSL on 26th February 2015 by David Ramos of Stanford University. The fix was developed by Stephen Henson and Matt Caswell of the OpenSSL development team. Reclassified: RSA silently downgrades to EXPORT_RSA [Client] (CVE-2015-0204) ============================================================================ Severity: High This security issue was previously announced by the OpenSSL project and classified as "low" severity. This severity rating has now been changed to "high". This was classified low because it was originally thought that server RSA export ciphersuite support was rare: a client was only vulnerable to a MITM attack against a server which supports an RSA export ciphersuite. Recent studies have shown that RSA export ciphersuites support is far more common. This issue affects OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 22nd October 2014 by Karthikeyan Bhargavan of the PROSECCO team at INRIA. The fix was developed by Stephen Henson of the OpenSSL core team. It was previously announced in the OpenSSL security advisory on 8th January 2015. Multiblock corrupted pointer (CVE-2015-0290) ============================================ Severity: Moderate OpenSSL 1.0.2 introduced the "multiblock" performance improvement. This feature only applies on 64 bit x86 architecture platforms that support AES NI instructions. A defect in the implementation of "multiblock" can cause OpenSSL's internal write buffer to become incorrectly set to NULL when using non-blocking IO. Typically, when the user application is using a socket BIO for writing, this will only result in a failed connection. However if some other BIO is used then it is likely that a segmentation fault will be triggered, thus enabling a potential DoS attack. This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 users should upgrade to 1.0.2a. This issue was reported to OpenSSL on 13th February 2015 by Daniel Danner and Rainer Mueller. The fix was developed by Matt Caswell of the OpenSSL development team. Segmentation fault in DTLSv1_listen (CVE-2015-0207) =================================================== Severity: Moderate The DTLSv1_listen function is intended to be stateless and processes the initial ClientHello from many peers. It is common for user code to loop over the call to DTLSv1_listen until a valid ClientHello is received with an associated cookie. A defect in the implementation of DTLSv1_listen means that state is preserved in the SSL object from one invocation to the next that can lead to a segmentation fault. Errors processing the initial ClientHello can trigger this scenario. An example of such an error could be that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only server. This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 DTLS users should upgrade to 1.0.2a. This issue was reported to OpenSSL on 27th January 2015 by Per Allansson. The fix was developed by Matt Caswell of the OpenSSL development team. Segmentation fault in ASN1_TYPE_cmp (CVE-2015-0286) =================================================== Severity: Moderate The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was discovered and fixed by Stephen Henson of the OpenSSL development team. Segmentation fault for invalid PSS parameters (CVE-2015-0208) ============================================================= Severity: Moderate The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and invalid parameters. Since these routines are used to verify certificate signature algorithms this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 users should upgrade to 1.0.2a This issue was was reported to OpenSSL on 31st January 2015 by Brian Carpenter and a fix developed by Stephen Henson of the OpenSSL development team. ASN.1 structure reuse memory corruption (CVE-2015-0287) ======================================================= Severity: Moderate Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. Such reuse is and has been strongly discouraged and is believed to be rare. Applications that parse structures containing CHOICE or ANY DEFINED BY components may be affected. Certificate parsing (d2i_X509 and related functions) are however not affected. OpenSSL clients and servers are not affected. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was discovered by Emilia Käsper and a fix developed by Stephen Henson of the OpenSSL development team. PKCS7 NULL pointer dereferences (CVE-2015-0289) =============================================== Severity: Moderate The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing. Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was reported to OpenSSL on February 16th 2015 by Michal Zalewski (Google) and a fix developed by Emilia Käsper of the OpenSSL development team. Base64 decode (CVE-2015-0292) ============================= Severity: Moderate A vulnerability existed in previous versions of OpenSSL related to the processing of base64 encoded data. Any code path that reads base64 data from an untrusted source could be affected (such as the PEM processing routines). Maliciously crafted base 64 data could trigger a segmenation fault or memory corruption. This was addressed in previous versions of OpenSSL but has not been included in any security advisory until now. This issue affects OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1h. OpenSSL 1.0.0 users should upgrade to 1.0.0m. OpenSSL 0.9.8 users should upgrade to 0.9.8za. The fix for this issue can be identified by commits d0666f289a (1.0.1), 84fe686173 (1.0.0) and 9febee0272 (0.9.8). This issue was originally reported by Robert Dugal and subsequently by David Ramos. DoS via reachable assert in SSLv2 servers (CVE-2015-0293) ========================================================= Severity: Moderate A malicious client can trigger an OPENSSL_assert (i.e., an abort) in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was discovered by Sean Burford (Google) and Emilia Käsper (OpenSSL development team) in March 2015 and the fix was developed by Emilia Käsper. Empty CKE with client auth and DHE (CVE-2015-1787) ================================================== Severity: Moderate If client auth is used then a server can seg fault in the event of a DHE ciphersuite being selected and a zero length ClientKeyExchange message being sent by the client. This could be exploited in a DoS attack. This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 users should upgrade to 1.0.2a. This issue was discovered and the fix was developed by Matt Caswell of the OpenSSL development team. Handshake with unseeded PRNG (CVE-2015-0285) ============================================ Severity: Low Under certain conditions an OpenSSL 1.0.2 client can complete a handshake with an unseeded PRNG. The conditions are: - The client is on a platform where the PRNG has not been seeded automatically, and the user has not seeded manually - A protocol specific client method version has been used (i.e. not SSL_client_methodv23) - A ciphersuite is used that does not require additional random data from the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA). If the handshake succeeds then the client random that has been used will have been generated from a PRNG with insufficient entropy and therefore the output may be predictable. For example using the following command with an unseeded openssl will succeed on an unpatched platform: openssl s_client -psk 1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA This issue affects OpenSSL version: 1.0.2 OpenSSL 1.0.2 users should upgrade to 1.0.2a. This issue was discovered and the fix was developed by Matt Caswell of the OpenSSL development team. Use After Free following d2i_ECPrivatekey error (CVE-2015-0209) =============================================================== Severity: Low A malformed EC private key file consumed via the d2i_ECPrivateKey function could cause a use after free condition. This, in turn, could cause a double free in several private key parsing functions (such as d2i_PrivateKey or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption for applications that receive EC private keys from untrusted sources. This scenario is considered rare. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was discovered by the BoringSSL project and fixed in their commit 517073cd4b. The OpenSSL fix was developed by Matt Caswell of the OpenSSL development team. X509_to_X509_REQ NULL pointer deref (CVE-2015-0288) =================================================== Severity: Low The function X509_to_X509_REQ will crash with a NULL pointer dereference if the certificate key is invalid. This function is rarely used in practice. This issue affects all current OpenSSL versions: 1.0.2, 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.2 users should upgrade to 1.0.2a OpenSSL 1.0.1 users should upgrade to 1.0.1m. OpenSSL 1.0.0 users should upgrade to 1.0.0r. OpenSSL 0.9.8 users should upgrade to 0.9.8zf. This issue was discovered by Brian Carpenter and a fix developed by Stephen Henson of the OpenSSL development team. Note ==== As per our previous announcements and our Release Strategy (https://www.openssl.org/about/releasestrat.html), support for OpenSSL versions 1.0.0 and 0.9.8 will cease on 31st December 2015.

Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. (CVE-2015-0286) An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input (such as a PEM file) could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded. (CVE-2015-0292) A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293) A use-after-free flaw was found in the way OpenSSL imported malformed Elliptic Curve private keys. A specially crafted key file could cause an application using OpenSSL to crash when imported. (CVE-2015-0209) An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash. A specially crafted X.509 certificate could cause an application using OpenSSL to crash if the application attempted to convert the certificate to a certificate request. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. (CVE-2015-0289) Red Hat would like to thank the OpenSSL project for reporting CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289, CVE-2015-0292, and CVE-2015-0293. This update also fixes the following bug: * When a wrapped Advanced Encryption Standard (AES) key did not require any padding, it was incorrectly padded with 8 bytes, which could lead to data corruption and interoperability problems. With this update, the rounding algorithm in the RFC 5649 key wrapping implementation has been fixed. As a result, the wrapped key conforms to the specification, which prevents the described problems. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. 4.
