CVEID: CVE-2015-0287**
DESCRIPTION:** OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an error related to the reuse of a structure in ASN.1 parsing. An attacker could exploit this vulnerability using an invalid write to corrupt memory and execute arbitrary code on the system.
CVSS Base Score: 7.5
