TITLE

Fiery Network Controllers for Xerox DocuColor 242/252/260 Printer/Copier use a vulnerable version of OpenSSL

DESCRIPTION

The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remote attackers to cause a denial of service (daemon crash) via crafted data from a TLS client. Fiery Network Controllers for Xerox DocuColor 242/252/260 Printer/Copier use a vulnerable version of OpenSSL (0.9.8o). OpenSSL prone to multiple security vulnerabilities. An attacker may leverage these issues to obtain sensitive information, cause a denial-of-service condition and perform unauthorized actions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20566.www2.hp.com/portal/site/hpsc/public/kb/ docDisplay?docId=emr_na-c03360041 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c03360041 Version: 1 HPSBMU02786 SSRT100877 rev.1 - HP System Management Homepage (SMH) Running on Linux and Windows, Remote Unauthorized Access, Disclosure of Information, Data Modification, Denial of Service (DoS), Execution of Arbitrary Code NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Content-Disposition: inline ==========================================================================Ubuntu Security Notice USN-1357-1 February 09, 2012 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: Multiple vulnerabilities exist in OpenSSL that could expose sensitive information or cause applications to crash. Software Description: - openssl: Secure Socket Layer (SSL) binary and related cryptographic tools Details: It was discovered that the elliptic curve cryptography (ECC) subsystem in OpenSSL, when using the Elliptic Curve Digital Signature Algorithm (ECDSA) for the ECDHE_ECDSA cipher suite, did not properly implement curves over binary fields. This could allow an attacker to determine private keys via a timing attack. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1945) Adam Langley discovered that the ephemeral Elliptic Curve Diffie-Hellman (ECDH) functionality in OpenSSL did not ensure thread safety while processing handshake messages from clients. This could allow a remote attacker to cause a denial of service via out-of-order messages that violate the TLS protocol. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-3210) Nadhem Alfardan and Kenny Paterson discovered that the Datagram Transport Layer Security (DTLS) implementation in OpenSSL performed a MAC check only if certain padding is valid. This could allow a remote attacker to recover plaintext. This could allow a remote attacker to cause a denial of service. This could allow a remote attacker to cause a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-4109) It was discovered that OpenSSL, in certain circumstances involving ECDH or ECDHE cipher suites, used an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves. This could allow a remote attacker to obtain the private key of a TLS server via multiple handshake attempts. This issue only affected Ubuntu 8.04 LTS. (CVE-2011-4576) Andrew Chi discovered that OpenSSL, when RFC 3779 support is enabled, could trigger an assert when handling an X.509 certificate containing certificate-extension data associated with IP address blocks or Autonomous System (AS) identifiers. This could allow a remote attacker to cause a denial of service. This could allow a remote attacker to cause a denial of service. This issue only affected Ubuntu 11.10. (CVE-2012-0027) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: libssl1.0.0 1.0.0e-2ubuntu4.2 openssl 1.0.0e-2ubuntu4.2 Ubuntu 11.04: libssl0.9.8 0.9.8o-5ubuntu1.2 openssl 0.9.8o-5ubuntu1.2 Ubuntu 10.10: libssl0.9.8 0.9.8o-1ubuntu4.6 openssl 0.9.8o-1ubuntu4.6 Ubuntu 10.04 LTS: libssl0.9.8 0.9.8k-7ubuntu8.8 openssl 0.9.8k-7ubuntu8.8 Ubuntu 8.04 LTS: libssl0.9.8 0.9.8g-4ubuntu3.15 openssl 0.9.8g-4ubuntu3.15 After a standard system update you need to reboot your computer to make all the necessary changes.

DTLS Plaintext Recovery Attack (CVE-2011-4108) ============================================== Nadhem Alfardan and Kenny Paterson have discovered an extension of the Vaudenay padding oracle attack on CBC mode encryption which enables an efficient plaintext recovery attack against the OpenSSL implementation of DTLS. Their attack exploits timing differences arising during decryption processing. A research paper describing this attack can be found at http://www.isg.rhul.ac.uk/~kp/dtls.pdf Thanks go to Nadhem Alfardan and Kenny Paterson of the Information Security Group at Royal Holloway, University of London (www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann <seggelmann@fh-muenster.de> and Michael Tuexen <tuexen@fh-muenster.de> for preparing the fix. Affected users should upgrade to OpenSSL 1.0.0f or 0.9.8s. Double-free in Policy Checks (CVE-2011-4109) ============================================ If X509_V_FLAG_POLICY_CHECK is set in OpenSSL 0.9.8, then a policy check failure can lead to a double-free. The bug does not occur unless this flag is set. Users of OpenSSL 1.0.0 are not affected. This flaw was discovered by Ben Laurie and a fix provided by Emilia Kasper <ekasper@google.com> of Google. Affected users should upgrade to OpenSSL 0.9.8s. Uninitialized SSL 3.0 Padding (CVE-2011-4576) ============================================= OpenSSL prior to 1.0.0f and 0.9.8s failed to clear the bytes used as block cipher padding in SSL 3.0 records. This affects both clients and servers that accept SSL 3.0 handshakes: those that call SSL_CTX_new with SSLv3_{server|client}_method or SSLv23_{server|client}_method. It does not affect TLS. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could include sensitive contents of previously freed memory. However, in practice, most deployments do not use SSL_MODE_RELEASE_BUFFERS and therefore have a single write buffer per connection. That write buffer is partially filled with non-sensitive, handshake data at the beginning of the connection and, thereafter, only records which are longer any any previously sent record leak any non-encrypted data. This, combined with the small number of bytes leaked per record, serves to limit to severity of this issue. Thanks to Adam Langley <agl@chromium.org> for identifying and fixing this issue. Affected users should upgrade to OpenSSL 1.0.0f or 0.9.8s. Malformed RFC 3779 Data Can Cause Assertion Failures (CVE-2011-4577) ==================================================================== RFC 3779 data can be included in certificates, and if it is malformed, may trigger an assertion failure. This could be used in a denial-of-service attack. Note, however, that in the standard release of OpenSSL, RFC 3779 support is disabled by default, and in this case OpenSSL is not vulnerable. Builds of OpenSSL are vulnerable if configured with "enable-rfc3779". Thanks to Andrew Chi, BBN Technologies, for discovering the flaw, and Rob Austein <sra@hactrn.net> for fixing it. Affected users should upgrade to OpenSSL 1.0.0f or 0.9.8s. SGC Restart DoS Attack (CVE-2011-4619) ====================================== Support for handshake restarts for server gated cryptograpy (SGC) can be used in a denial-of-service attack. Thanks to George Kadianakis <desnacked@gmail.com> for identifying this issue and to Adam Langley <agl@chromium.org> for fixing it. Affected users should upgrade to OpenSSL 1.0.0f or 0.9.8s. This could be used in a denial-of-service attack. Only users of the OpenSSL GOST ENGINE are affected by this bug. Thanks to Andrey Kulikov <amdeich@gmail.com> for identifying and fixing this issue. Affected users should upgrade to OpenSSL 1.0.0f. References ========== URL for this Security Advisory: https://www.openssl.org/news/secadv_20120104.txt
