A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in OpenSSL.
It was discovered that OpenSSL incorrectly handled malformed EC private key files. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2015-0209)
Stephen Henson discovered that OpenSSL incorrectly handled comparing ASN.1 boolean types. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-0286)
Emilia Käsper discovered that OpenSSL incorrectly handled ASN.1 structure reuse. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2015-0287)
Brian Carpenter discovered that OpenSSL incorrectly handled invalid certificate keys. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-0288)
Michal Zalewski discovered that OpenSSL incorrectly handled missing outer ContentInfo when parsing PKCS#7 structures. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2015-0289)
Robert Dugal and David Ramos discovered that OpenSSL incorrectly handled decoding Base64 encoded data. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2015-0292)
Sean Burford and Emilia Käsper discovered that OpenSSL incorrectly handled specially crafted SSLv2 CLIENT-MASTER-KEY messages. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-0293)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
