TITLE

OpenSSL ‘ d2i_ECPrivateKey 'Reuse the function after the release of the vulnerability

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. 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. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations (CVE-2015-0204). The verification of md5 checksums and GPG signatures is performed automatically for you. Additionally a follow-up fix for CVE-2015-0209 is applied. Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit. 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+deb7u16. We recommend that you upgrade your openssl packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat JBoss Web Server 3.0.3 security update Advisory ID: RHSA-2016:1089-01 Product: Red Hat JBoss Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-1089.html Issue date: 2016-05-17 CVE Names: CVE-2015-0209 CVE-2015-5312 CVE-2015-5345 CVE-2015-5346 CVE-2015-5351 CVE-2015-7497 CVE-2015-7498 CVE-2015-7499 CVE-2015-7500 CVE-2015-7941 CVE-2015-7942 CVE-2015-8035 CVE-2015-8241 CVE-2015-8242 CVE-2015-8317 CVE-2015-8710 CVE-2016-0706 CVE-2016-0714 CVE-2016-0763 ===================================================================== 1. Summary: Red Hat JBoss Web Server 3.0.3 is now available for Red Hat Enterprise Linux 6 and 7, Solaris, and Microsoft Windows from the Customer Portal. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Description: Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. This release of Red Hat JBoss Web Server 3.0.3 serves as a replacement for Red Hat JBoss Web Server 3.0.2, and includes bug fixes and enhancements, which are documented in the Release Notes documented linked to in the References. Security Fix(es): * Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application. (CVE-2015-5312, CVE-2015-7497, CVE-2015-7498, CVE-2015-7499, CVE-2015-7500, CVE-2015-7942, CVE-2015-8035, CVE-2015-8710, CVE-2015-7941, CVE-2015-8241, CVE-2015-8242, CVE-2015-8317) * A session fixation flaw was found in the way Tomcat recycled the requestedSessionSSL field. If at least one web application was configured to use the SSL session ID as the HTTP session ID, an attacker could reuse a previously used session ID for further requests. (CVE-2015-5346) * A CSRF flaw was found in Tomcat's the index pages for the Manager and Host Manager applications. These applications included a valid CSRF token when issuing a redirect as a result of an unauthenticated request to the root of the web application. This token could then be used by an attacker to perform a CSRF attack. (CVE-2015-5351) * It was found that several Tomcat session persistence mechanisms could allow a remote, authenticated user to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that placed a crafted object in a session. (CVE-2016-0714) * A security manager bypass flaw was found in Tomcat that could allow remote, authenticated users to access arbitrary application data, potentially resulting in a denial of service. (CVE-2015-0209) * It was found that Tomcat could reveal the presence of a directory even when that directory was protected by a security constraint. A user could make a request to a directory via a URL not ending with a slash and, depending on whether Tomcat redirected that request, could confirm whether that directory existed. (CVE-2015-5345) * It was found that Tomcat allowed the StatusManagerServlet to be loaded by a web application when a security manager was configured. This allowed a web application to list all deployed web applications and expose sensitive information such as session IDs. (CVE-2016-0706) Red Hat would like to thank the GNOME project for reporting CVE-2015-7497, CVE-2015-7498, CVE-2015-7499, CVE-2015-7500, CVE-2015-8241, CVE-2015-8242, and CVE-2015-8317.

I. Background FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. Abstract Syntax Notation One (ASN.1) is a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking, which enables representation of objects that are independent of machine-specific encoding technique. II. Problem Description A malformed elliptic curve private key file could cause a use-after-free condition in the d2i_ECPrivateKey function. [CVE-2015-0209] An attempt to compare ASN.1 boolean types will cause the ASN1_TYPE_cmp function to crash with an invalid read. [CVE-2015-0286] Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. [CVE-2015-0287] The function X509_to_X509_REQ will crash with a NULL pointer dereference if the certificate key is invalid. [CVE-2015-0288] The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. [CVE-2015-0289] A malicious client can trigger an OPENSSL_assert in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message. [CVE-2015-0293] III. [CVE-2015-0209] A remote attacker who is able to send specifically crafted certificates may be able to crash an OpenSSL client or server. [CVE-2015-0286] An attacker who can cause invalid writes with applications that parse structures containing CHOICE or ANY DEFINED BY components and reusing the structures may be able to cause them to crash. Such reuse is believed to be rare. OpenSSL clients and servers are not affected. [CVE-2015-0287] An attacker may be able to crash applications that create a new certificate request with subject name the same as in an existing, specifically crafted certificate. This usage is rare in practice. [CVE-2015-0288] An attacker may be able to crash applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures with specifically crafted certificates. [CVE-2015-0289] A malicious client can trigger an OPENSSL_assert in servers that both support SSLv2 and enable export cipher suites by sending a carefully crafted SSLv2 CLIENT-MASTER-KEY message, resulting in a Denial of Service. [CVE-2015-0293] Note that two issues in the original OpenSSL advisory, CVE-2015-0204 and CVE-2015-0292, were already addressed by FreeBSD-SA-15:01.openssl and FreeBSD-EN-15:02.openssl. IV. Workaround No workaround is available. V.
