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. 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. rPath Security Advisory: 2006-0175-2 Published: 2006-09-28 Updated: 2006-09-29 Resolved issue in patch for CVE-2006-2940 Products: rPath Linux 1 Rating: Major Exposure Level Classification: Remote Deterministic Unauthorized Access Updated Versions: openssl=/conary.rpath.com@rpl:devel//1/0.9.7f-10.5-1 openssl-scripts=/conary.rpath.com@rpl:devel//1/0.9.7f-10.5-1 References: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2937 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2940 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3738 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4343 http://issues.rpath.com/browse/RPL-613 Description: Previous versions of the openssl package are vulnerable to multiple attacks. In particular, any connection that the mysql daemon will accept may be vulnerable. In the default configuration of mysql, that would be a local unauthorized access vulnerability, but mysql can be configured to listen for network connections from remote hosts, which would then enable remote unauthorized access. Any program that calls the SSL_get_shared_ciphers() function may be vulnerable. 29 September 2006 Update: The initial fix for this vulnerability was incomplete, and the fault in the fix could enable a Denial of Service attack in some cases of the attack described in CVE-2006-2940. _______________________________________________ Full-Disclosure - We believe in it. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:172-1 http://www.mandriva.com/security/ _______________________________________________________________________ Package : openssl Date : October 2, 2006 Affected: 2006.0, 2007.0, Corporate 3.0, Corporate 4.0, Multi Network Firewall 2.0 _______________________________________________________________________ Problem Description: Dr S N Henson of the OpenSSL core team and Open Network Security recently developed an ASN1 test suite for NISCC (www.niscc.gov.uk). During the parsing of certain invalid ASN1 structures an error condition is mishandled. This can result in an infinite loop which consumes system memory. (CVE-2006-2937) 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. (CVE-2006-2940) Tavis Ormandy and Will Drewry of the Google Security Team discovered a buffer overflow in the SSL_get_shared_ciphers utility function, used by some applications such as exim and mysql. An attacker could send a list of ciphers that would overrun a buffer. (CVE-2006-3738) Tavis Ormandy and Will Drewry of the Google Security Team discovered a possible DoS in the sslv2 client code. (CVE-2006-4343) Updated packages are patched to address these issues. Update: There was an error in the original published patches for CVE-2006-2940. New packages have corrected this issue. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2937

Software updates for the Apache-based Web Server are available from: http://h20293.www2.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE HP-UX B.11.00, B.11.11 and HP-UX B.11.23 require the Apache-based Web Server v.2.0.58.01 or subsequent. Apache Update Procedure Check for Apache Installation ----------------------------- To determine if the Apache web server from HP is installed on your system, use Software Distributor's swlist command. All three revisions of the product may co-exist on a single system. For example, the results of the command swlist -l product | grep -I apache hpuxwsAPACHE B.2.0.55.00 HP-UX Apache-based Web Server Stop Apache ------------- Before updating, make sure the previous Apache binary is stopped. If Apache is not stopped, the installation would be successful but the new version would be prevented from starting until a later time. After determining which Apache is installed, stop Apache with the following commands: for hpuxwsAPACHE: /opt/hpws/apache[32]/bin/apachectl stop Download and Install Apache -------------------------- Download Apache from Software Depot. http://h20293.www2.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE Verify successful download by comparing the cksum with the value specified on the installation web page. Use SD to swinstall the depot. Installation of this new revision of HP Apache over an existing HP Apache installation is supported, while installation over a non-HP Apache is NOT supported. Removing Apache Installation --------------------------- The potential vulnerability can also be resolved by removing Apache rather than installing a newer revision. To remove Apache use both Software Distributor's "swremove" command and also "rm -rf" the home location as specified in the rc.config.d file "HOME" variables. %ls /etc/rc.config.d | \ grep apache hpapache2conf hpws_apache[32]conf MANUAL ACTIONS: Yes - Update plus other actions Install the revision of the product. PRODUCT SPECIFIC INFORMATION HP-UX Security Patch Check: Security Patch Check revision B.02.00 analyzes all HP-issued Security Bulletins to provide a subset of recommended actions that potentially affect a specific HP-UX system.
