Vulnerability Assessment Details

[GLSA-200610-11] OpenSSL: Multiple vulnerabilities

Vulnerability Assessment Summary
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.
