OpenSSL < 0.9.8s Multiple Vulnerabilities

High Nessus Plugin ID 57459

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.9


The remote web server has multiple SSL-related vulnerabilities.


According to its banner, the remote web server is running a version of OpenSSL older than 0.9.8s. Such versions have the following vulnerabilities :

- An error exists related to ECDSA signatures and binary curves. The implementation of curves over binary fields could allow a remote, unauthenticated attacker to determine private key material via timing attacks.

- The Datagram Transport Layer Security (DTLS) implementation is vulnerable to plaintext recovery attacks when decrypting in CBC mode. (CVE-2011-4108)

- A double-free error exists during a policy check failure if the flag 'X509_V_FLAG_POLICY_CHECK' is set.

- An error exists related to SSLv3.0 records that can lead to disclosure of uninitialized memory because the library does not clear all bytes used as block cipher padding. (CVE-2011-4576)

- An error exists related to RFC 3779 processing that can allow denial of service attacks. Note that this functionality is not enabled by default and must be configured at compile time via the 'enable-rfc3779' option. (CVE-2011-4577)

- An error exists related to handshake restarts for server gated cryptography (SGC) that can allow denial of service attacks. (CVE-2011-4619)


Upgrade to OpenSSL 0.9.8s or later.
