  - A NULL pointer dereference flaw exists in the     BN_hex2bn() and BN_dec2bn() functions. A remote attacker     can exploit this to trigger a heap corruption, resulting     in the execution of arbitrary code. (CVE-2016-0797)

  - A denial of service vulnerability exists due to improper     handling of invalid usernames. A remote attacker can     exploit this, via a specially crafted username, to leak     300 bytes of memory per connection, exhausting available     memory resources. (CVE-2016-0798)

  - Multiple memory corruption issues exist that allow a     remote attacker to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-0799)

  - A heap buffer overflow condition exists 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     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)

  - A remote code execution vulnerability exists in the     ASN.1 encoder due to an underflow condition that occurs     when attempting to encode the value zero represented as     a negative integer. An unauthenticated, remote attacker     can exploit this to corrupt memory, resulting in the     execution of arbitrary code. (CVE-2016-2108)

  - Multiple unspecified flaws exist 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)

  - Multiple integer overflow conditions exist in s3_srvr.c,     ssl_sess.c, and t1_lib.c due to improper use of pointer     arithmetic for heap-buffer boundary checks. An     unauthenticated, remote attacker can exploit this to     cause a denial of service. (CVE-2016-2177)

  - An information disclosure vulnerability exists in the     dsa_sign_setup() function in dsa_ossl.c due to a failure     to properly ensure the use of constant-time operations.

The self-reported SGOS version installed on the remote Blue Coat ProxySG device is 6.5.x prior to 6.5.9.8 or 6.6.x prior to 6.6.4.1. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL :

  - Multiple flaws exist 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.
    Note that this issue does not affect the SG300 and SG600     hardware platforms. (CVE-2016-2107)

  - A remote code execution vulnerability exists in the     ASN.1 encoder due to an underflow condition that occurs     when attempting to encode the value zero represented as     a negative integer. An unauthenticated, remote attacker     can exploit this to corrupt memory, resulting in the     execution of arbitrary code. (CVE-2016-2108)

  - Multiple unspecified flaws exist 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. Note that this issue only affects management     connections. (CVE-2016-2109)

Several vulnerabilities were discovered in OpenSSL, a Secure Socket Layer toolkit.

CVE-2016-2105

Guido Vranken discovered that an overflow can occur in the function EVP_EncodeUpdate(), used for Base64 encoding, if an attacker can supply a large amount of data. This could lead to a heap corruption.

CVE-2016-2106

Guido Vranken discovered that an overflow can occur in the function EVP_EncryptUpdate() if an attacker can supply a large amount of data.
This could lead to a heap corruption.

CVE-2016-2107

Juraj Somorovsky discovered a padding oracle in the AES CBC cipher implementation based on the AES-NI instruction set. This could allow an attacker to decrypt TLS traffic encrypted with one of the cipher suites based on AES CBC.

CVE-2016-2108

David Benjamin from Google discovered that two separate bugs in the ASN.1 encoder, related to handling of negative zero integer values and large universal tags, could lead to an out-of-bounds write.

CVE-2016-2109

Brian Carpenter discovered that when ASN.1 data is read from a BIO using functions such as d2i_CMS_bio(), a short invalid encoding can casuse allocation of large amounts of memory potentially consuming excessive resources or exhausting memory.

CVE-2016-2176

Guido Vranken discovered that ASN.1 Strings that are over 1024 bytes can cause an overread in applications using the X509_NAME_oneline() function on EBCDIC systems. This could result in arbitrary stack data being returned in the buffer.

An update for openssl is now available for Red Hat Enterprise Linux 6.7 Extended Update Support.

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)
