Description

It was discovered that OpenSSL incorrectly handled memory in the ssl3_read_bytes() function. A remote attacker could use this issue to possibly cause OpenSSL to crash, resulting in a denial of service. (CVE-2010-5298)

It was discovered that OpenSSL incorrectly handled memory in the do_ssl3_write() function. A remote attacker could use this issue to possibly cause OpenSSL to crash, resulting in a denial of service. (CVE-2014-0198).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
