OpenSSL < 0.9.8l Multiple Vulnerabilities

medium Nessus Plugin ID 17765
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 is different from CVSS.

VPR Score: 6.7

Synopsis

The remote server is affected by multiple vulnerabilities.

Description

According to its banner, the remote server is running a version of OpenSSL that is earlier than 0.9.8l. As such, it may be affected by multiple vulnerabilities :

- A remote attacker could crash the server by sending malformed ASN.1 data. This flaw only affects some architectures, Win64 and other unspecified platforms. (CVE-2009-0789)

- A remote attacker could saturate the server by sending a big number of 'future epoch' DTLS records. (CVE-2009-1377)

- A remote attacker could saturate the server by sending duplicate DTLS records, or DTLS records with too big sequence numbers. (CVE-2009-1378)

- A remote attacker could spoof certificates by computing MD2 hash collisions. (CVE-2009-2409)

Solution

Upgrade to OpenSSL 0.9.8l or later.
