CVE-2006-2937

TITLE

OpenSSL may fail to properly parse invalid ASN.1 structures

DESCRIPTION

OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled error condition. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. An attacker may exploit this issue to cause applications that use the vulnerable library to consume excessive CPU and memory resources and crash, denying further service to legitimate users. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c00967144 Version: 1 HPSBTU02207 SSRT061213, SSRT061239, SSRT071304 rev.1 - HP Tru64 UNIX SSL and BIND Remote Arbitrary Code Execution or Denial of Service (DoS) NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

PRODUCT SPECIFIC INFORMATION The HP Tru64 UNIX v 5.1B-3 and v 5.1B-4 ERP kits distribute two patches: -OpenSSL 0.9.8d -BIND 9.2.8 built with OpenSSL 0.9.8d Note: HP Tru64 UNIX v 5.1A, v 4.0G, and v 4.0F releases did not distribute OpenSSL and so their ERP kits provide only the BIND 9.2.8 patch that has been built with OpenSSL 0.9.8d Customers who have been using OpenSSL on HP Tru64 UNIX v 5.1B-3 and v 5.1B-4 should install the OpenSSL patch from the ERP kit appropriate for their base operating system version. The HP Insight Management Agents for Tru64 UNIX patch contains OpenSSL 0.9.8d and is applicable for HP Tru64 UNIX v 5.1A, v 5.1B-3, and v 5.1B-4.

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. _______________________________________________ Full-Disclosure - We believe in it.

OpenSSL Security Advisory [28th September 2006] New OpenSSL releases are now available to correct four security issues. ASN.1 Denial of Service Attacks (CVE-2006-2937, CVE-2006-2940) ============================================================== Vulnerability ------------- Dr. S. N. Henson recently developed an ASN.1 test suite for NISCC (www.niscc.gov.uk). 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 (CVE-2006-2937). (This issue did not affect OpenSSL versions prior to 0.9.7) 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 (CVE-2006-2940). Any code which uses OpenSSL to parse ASN.1 data from untrusted sources is affected. This includes SSL servers which enable client authentication and S/MIME applications. Acknowledgements ---------------- The OpenSSL team thank Dr S. N. Henson of Open Network Security and NISCC for funding the ASN.1 test suite project. An attacker could send a list of ciphers to an application that uses this function and overrun a buffer (CVE-2006-3738). Acknowledgements ---------------- The OpenSSL team thank Tavis Ormandy and Will Drewry of the Google Security Team for reporting this issue. SSLv2 Client Crash (CVE-2006-4343) ================================== Vulnerability ------------- A flaw in the SSLv2 client code was discovered. Acknowledgements ---------------- The OpenSSL team thank Tavis Ormandy and Will Drewry of the Google Security Team for reporting this issue. Recommendations =============== These vulnerabilities are resolved in the following versions of OpenSSL: - in the 0.9.7 branch, version 0.9.7l (or later); - in the 0.9.8 branch, version 0.9.8d (or later). OpenSSL 0.9.8d and OpenSSL 0.9.7l are available for download via HTTP and FTP from the following master locations (you can find the various FTP mirrors under https://www.openssl.org/source/mirror.html): o https://www.openssl.org/source/ o ftp://ftp.openssl.org/source/ The distribution file names are: o openssl-0.9.8d.tar.gz MD5 checksum: 8ed1853538e1d05a1f5ada61ebf8bffa SHA1 checksum: 4136fba00303a3d319d2052bfa8e1f09a2e12fc2 o openssl-0.9.7l.tar.gz MD5 checksum: b21d6e10817ddeccf5fbe1379987333e SHA1 checksum: f0e4136639b10cbd1227c4f7350ff7ad406e575d The checksums were calculated using the following commands: openssl md5 openssl-0.9*.tar.gz openssl sha1 openssl-0.9*.tar.gz After upgrading make sure to recompile any applications statically linked to OpenSSL libraries and restart all applications that use OpenSSL.
