OpenSSL: Multiple vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200610-11 (OpenSSL: Multiple vulnerabilities) Tavis Ormandy and Will Drewry, both of the Google Security Team, discovered that the SSL_get_shared_ciphers() function contains a buffer overflow vulnerability, and that the SSLv2 client code contains a flaw leading to a crash. Additionally Dr. Stephen N. Henson found that the ASN.1 handler contains two Denial of Service vulnerabilities: while parsing an invalid ASN.1 structure and while handling certain types of public key. Impact A possible hacker could trigger the buffer overflow vulnerability by sending a malicious suite of ciphers to an application using the vulnerable function, and thus execute arbitrary code with the rights of the user running the application. A possible hacker could also consume CPU and/or memory by exploiting the Denial of Service vulnerabilities. Finally a malicious server could crash a SSLv2 client through the SSLv2 vulnerability. Workaround There is no known workaround at this time.
