Ubuntu alert USN-1424-1 (openssl)
========================================================================== Ubuntu Security Notice USN-1424-1 April 19, 2012 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: An application using OpenSSL could be made to crash or run programs if it opened a specially crafted file. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: It was discovered that OpenSSL could be made to dereference a NULL pointer when processing S/MIME messages. A remote attacker could use this to cause a denial of service. These issues did not affect Ubuntu 8.04 LTS. (CVE-2006-7250, CVE-2012-1165) Tavis Ormandy discovered that OpenSSL did not properly perform bounds checking when processing DER data via BIO or FILE functions. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. (CVE-2012-2110) 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-2ubuntu4.4 Ubuntu 11.04: libssl0.9.8 0.9.8o-5ubuntu1.4 Ubuntu 10.04 LTS: libssl0.9.8 0.9.8k-7ubuntu8.10 Ubuntu 8.04 LTS: libssl0.9.8 0.9.8g-4ubuntu3.17 After a standard system update you need to reboot your computer to make all the necessary changes.
