Content-Disposition: inline ==========================================================================Ubuntu Security Notice USN-1451-1 May 24, 2012 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: Applications using OpenSSL in certain situations could be made to crash or expose sensitive information. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: Ivan Nestlerode discovered that the Cryptographic Message Syntax (CMS) and PKCS #7 implementations in OpenSSL returned early if RSA decryption failed. This could allow an attacker to expose sensitive information via a Million Message Attack (MMA). (CVE-2012-0884) It was discovered that an integer underflow was possible when using TLS 1.1, TLS 1.2, or DTLS with CBC encryption. This could allow a remote attacker to cause a denial of service. (CVE-2012-2333) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: libssl1.0.0 1.0.1-4ubuntu5.2 openssl 1.0.1-4ubuntu5.2 Ubuntu 11.10: libssl1.0.0 1.0.0e-2ubuntu4.6 openssl 1.0.0e-2ubuntu4.6 Ubuntu 11.04: libssl0.9.8 0.9.8o-5ubuntu1.7 openssl 0.9.8o-5ubuntu1.7 Ubuntu 10.04 LTS: libssl0.9.8 0.9.8k-7ubuntu8.13 openssl 0.9.8k-7ubuntu8.13 Ubuntu 8.04 LTS: libssl0.9.8 0.9.8g-4ubuntu3.19 openssl 0.9.8g-4ubuntu3.19 After a standard system update you need to reboot your computer to make all the necessary changes.
