Language:
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: 3.6
Synopsis
The remote server is affected by multiple vulnerabilities.Description
According to its banner, the remote server is running a version of OpenSSL prior to 0.9.8k. It is, therefore, affected by multiple vulnerabilities :- A denial of service vulnerability exists in the ASN1_STRING_print_ex() function due to improper string handling. A remote attacker can exploit this to cause an invalid memory access and application crash.
(CVE-2009-0590)
- A flaw exists in the CMS_verify() function due to improper handling of errors associated with malformed signed attributes. A remote attacker can exploit this to repudiate a signature that originally appeared to be valid but was actually invalid. (CVE-2009-0591)
- A denial of service vulnerability exists due to improper handling of malformed ASN.1 structures. A remote attacker can exploit this to cause an invalid memory access and application crash. (CVE-2009-0789)
- A memory leak exists in the SSL_free() function in ssl_lib.c. A remote attacker can exploit this to exhaust memory resources, resulting in a denial of service condition. (CVE-2009-5146)
Solution
Upgrade to OpenSSL version 0.9.8k or later.See Also
