The version of OpenSSL installed on the remote host is prior to 1.0.1t. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.1t advisory.

  - The X509_NAME_oneline function in crypto/x509/x509_obj.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h     allows remote attackers to obtain sensitive information from process stack memory or cause a denial of     service (buffer over-read) via crafted EBCDIC ASN.1 data. (CVE-2016-2176)

  - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in the ASN.1 BIO implementation in OpenSSL before     1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (memory consumption)     via a short invalid encoding. (CVE-2016-2109)

  - The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory     allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext     information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists     because of an incorrect fix for CVE-2013-0169. (CVE-2016-2107)

  - Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and     1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a     large amount of data. (CVE-2016-2106)

  - Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and     1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a     large amount of binary data. (CVE-2016-2105)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for openssl fixes the following issues :

  - CVE-2016-2108: Memory corruption in the ASN.1 encoder     (bsc#977617)

  - CVE-2016-2107: Padding oracle in AES-NI CBC MAC check     (bsc#977616)

  - CVE-2016-2105: EVP_EncodeUpdate overflow (bsc#977614)

  - CVE-2016-2106: EVP_EncryptUpdate overflow (bsc#977615)

  - CVE-2016-2109: ASN.1 BIO excessive memory allocation     (bsc#976942)

  - bsc#976943: Buffer overrun in ASN1_parse

  - bsc#977621: Preserve negotiated digests for SNI     (bsc#977621)

  - bsc#958501: Fix openssl enc -non-fips-allow option in     FIPS mode (bsc#958501)

An update for openssl is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es) :

* A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108)

* Two integer overflow flaws, leading to buffer overflows, were found in the way the EVP_EncodeUpdate() and EVP_EncryptUpdate() functions of OpenSSL parsed very large amounts of input data. A remote attacker could use these flaws to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105, CVE-2016-2106)

* It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2016-2107)

* Several flaws were found in the way BIO_*printf functions were implemented in OpenSSL. Applications which passed large amounts of untrusted data through these functions could crash or potentially execute code with the permissions of the user running such an application. (CVE-2016-0799, CVE-2016-2842)

* A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data. (CVE-2016-2109)

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The version of Oracle E-Business installed on the remote host is missing the October 2016 Oracle Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities :

  - A heap buffer overflow condition exists in the OpenSSL     subcomponent in the EVP_EncodeUpdate() function within     file crypto/evp/encode.c that is triggered when handling     a large amount of input data. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2016-2105)

  - A heap buffer overflow condition exists in the OpenSSL     subcomponent in the EVP_EncryptUpdate() function within     file crypto/evp/evp_enc.c that is triggered when     handling a large amount of input data after a previous     call occurs to the same function with a partial block.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2016-2106)

  - Multiple flaws exist in the OpenSSL subcomponent in the     aesni_cbc_hmac_sha1_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha1.c and the     aesni_cbc_hmac_sha256_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered     when the connection uses an AES-CBC cipher and AES-NI     is supported by the server. A man-in-the-middle attacker     can exploit these to conduct a padding oracle attack,     resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - Multiple unspecified flaws exist in the OpenSSL     subcomponent in the d2i BIO functions when reading ASN.1     data from a BIO due to invalid encoding causing a large     allocation of memory. An unauthenticated, remote     attacker can exploit these to cause a denial of service     condition through resource exhaustion. (CVE-2016-2109)

  - An out-of-bounds read error exists in the OpenSSL     subcomponent in the X509_NAME_oneline() function within     file crypto/x509/x509_obj.c when handling very long ASN1     strings. An unauthenticated, remote attacker can exploit     this to disclose the contents of stack memory.
