CVE-2006-3738

TITLE

OpenSSL SSLv2 client code fails to properly check for NULL

DESCRIPTION

Buffer overflow in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions has unspecified impact and remote attack vectors involving a long list of ciphers. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. The Oracle SYS.DBMS_AQ package is vulnerable to PL/SQL injection. This vulnerability may allow a remote, authenticated attacker to execute arbitrary PL/SQL commands on a vulnerable Oracle installation. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. Successfully exploiting this issue may result in the execution of arbitrary machine code in the context of applications that use the affected library. Failed exploit attempts may crash applications, denying service to legitimate users. Oracle has released a Critical Patch Update advisory for January 2007 to address these vulnerabilities for supported releases. Earlier unsupported releases are likely to be affected by these issues as well. The issues identified by the vendor affect all security properties of the Oracle products and present local and remote threats. Various levels of authorization are needed to leverage some of the issues, but other issues do not require any authorization. The most severe of the vulnerabilities could possibly expose affected computers to complete compromise. A flaw has also been reported in the BN_from_montgomery() function in crypto/bn/bn_mont.c when performing Montgomery multiplication. A local attacker could perform a side channel attack to retrieve the RSA private keys. Corrected: 2007-10-03 21:39:43 UTC (RELENG_6, 6.2-STABLE) 2007-10-03 21:40:35 UTC (RELENG_6_2, 6.2-RELEASE-p8) 2007-10-03 21:41:22 UTC (RELENG_6_1, 6.1-RELEASE-p20) 2007-10-03 21:42:00 UTC (RELENG_5, 5.5-STABLE) 2007-10-03 21:42:32 UTC (RELENG_5_5, 5.5-RELEASE-p16) CVE Name: CVE-2007-5135 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:http://security.FreeBSD.org/>. Background FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and 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. II. Problem Description A buffer overflow addressed in FreeBSD-SA-06:23.openssl has been found to be incorrectly fixed. III. IV. Workaround No workaround is available, but only applications using the SSL_get_shared_ciphers() function are affected. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 5-STABLE, or 6-STABLE, or to the RELENG_6_2, RELENG_6_1, or RELENG_5_5 security branch dated after the correction date. 2) To patch your present system: The following patch have been verified to apply to FreeBSD 5.5, 6.1, and 6.2 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-07:08/openssl.patch # fetch http://security.FreeBSD.org/patches/SA-07:08/openssl.patch.asc b) Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # cd /usr/src/secure/lib/libssl # make obj && make depend && make && make install VI.

ASN.1 Denial of Service Attack (1/2) During the parsing of certain invalid ASN.1 structures an error condition is mishandled. This can result in an infinite loop which consumes system memory. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2006-2937 [2] to the problem. 2. ASN.1 Denial of Service Attack (2/2) Certain types of public key can take disproportionate amounts of time to process. This could be used by an attacker in a denial of service attack. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2006-2940 [3] to the problem. 3. SSL_get_shared_ciphers() Buffer Overflow A buffer overflow was discovered in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that uses this function and overrun a buffer. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2006-3780 [4] to the problem. 4. SSLv2 Client Crash A flaw in the SSLv2 client code was discovered. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2006-4343 [5] to the problem. ________________________________________________________________________ References: [0] http://www.openssl.org/news/secadv_20060928.txt [1] http://www.openssl.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2937 [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2940 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3738 [5] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4343 ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@openpkg.org>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
