OpenSSL: Multiple Vulnerabilities (0.9.8 - 0.9.8l) (Windows)

Published: 2021-08-13 07:06:11
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Detection Type:
Remote Banner

Solution Type:
Vendor Patch

Summary:
OpenSSL is prone to multiple vulnerabilities.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The following vulnerabilities exist: - Multiple denial of service flaws in the DTLS implementation (CVE-2009-1377, CVE-2009-1378, CVE-2009-1387) - Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function could cause a client accessing a malicious DTLS server to crash (CVE-2009-1379) - It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code (CVE-2009-3245) - A Man-in-the-middle renegotiation attack (CVE-2009-3555) - A memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c allows remote attackers to cause a denial of service via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function (CVE-2009-4355)

Affected Versions:
OpenSSL 0.9.8 through 0.9.8l.

Recommendations:
Update to version 0.9.8m or later.

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".
