Critical
← View More Security Advisories

Synopsis

Nessus and SecurityCenter are potentially impacted by several vulnerabilities in OpenSSL that were recently disclosed and fixed. Note that due to the time involved in doing a full analysis of each issue, Tenable has opted to upgrade the included version of OpenSSL as a precaution, and to save time. The issues include:

  • CVE-2016-2107 - OpenSSL AES-NI CBC MAC Check Padding Oracle MitM Information Disclosure
  • CVE-2016-2105 - OpenSSL crypto/evp/encode.c EVP_EncodeUpdate() Function Heap Buffer Overflow Weakness
  • CVE-2016-2106 - OpenSSL crypto/evp/evp_enc.c EVP_EncryptUpdate() Function Heap Buffer Overflow Weakness
  • CVE-2016-2176 - OpenSSL crypto/x509/x509_obj.c X509_NAME_oneline() Function ASN1 Strings Handling Out-of-bounds Read Memory Disclosure
  • CVE-2016-2109 - OpenSSL crypto/asn1/a_d2i_fp.c ASN.1 BIO Length Field Handling Memory Exhaustion Remote DoS

Notes and caveats:

  • Nessus Agents are not affected by these issues, as they do not act as an SSL server.
  • The CVSS score reflects CVE-2016-2108.
  • Please note that Tenable strongly recommends products be installed on a subnet that is not Internet addressable.

Tenable has released version 6.7 that corresponds to the supported operating systems and architectures. This version bundles the updated OpenSSL library (1.0.2h), which is not affected. Version 6.7 of Nessus bundles OpenSSL 1.0.2h.
