OpenSSL DTLS Packets Multiple Denial of Service Vulnerabilities (Linux)
Published: 2009-05-28 05:14:08
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P
Summary:
OpenSSL is prone to multiple Denial of Service Vulnerabilities.
Impact:
Successful exploitation will allow attacker to cause denial-of-service
conditions, crash the client, and exhaust all memory.
Technical Details:
Multiple flaws are due to,
- The library does not limit the number of buffered DTLS records with a future epoch.
- An error when processing DTLS messages can be exploited to exhaust all available memory by sending a
large number of out of sequence handshake messages.
- A use-after-free error in the 'dtls1_retrieve_buffered_fragment()' function can be exploited to cause
a crash in a client context.
Affected Versions:
OpenSSL version 0.9.8 to version 0.9.8k and version 1.0.x versions 1.0.0 Beta2 and prior.
Detection Type:
Remote Banner Unreliable
Solution Type:
Vendor Patch

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
