OpenSSL 1.0.1 < 1.0.1t / 1.0.2 < 1.0.2h Multiple Vulnerabilities

According to its banner, the version of OpenSSL on the remote host is 1.0.1 prior to 1.0.1t, or 1.0.2 prior to 1.0.2h. It is therefore affected by the following vulnerabilities :

• A flaw exists in ‘crypto/asn1/a_d2i_fp.c’, which is triggered during the handling of large length fields in ASN.1 BIO. This may allow a remote attacker to exhaust memory resources, potentially crashing a process linked against the library.
• A flaw exists in the ‘aesni_cbc_hmac_sha1_cipher()’ function in ‘crypto/evp/e_aes_cbc_hmac_sha1.c’ and ‘aesni_cbc_hmac_sha256_cipher()’ function in ‘crypto/evp/e_aes_cbc_hmac_sha256.c’. The issue is triggered when a connection uses an AES CBC cipher and AES-NI is supported by the server. This may allow a MitM (Man-in-the-Middle) attacker to conduct a padding oracle attack to potentially decrypt traffic.
• A flaw in the ‘X509_NAME_oneline()’ function in ‘crypto/x509/x509_obj.c’ that is triggered when handling overly long ASN1 strings. This may allow a remote attacker to potentially disclose arbitrary stack memory contents.
• An overflow condition in the ‘EVP_EncryptUpdate()’ function in ‘crypto/evp/evp_enc.c’ is triggered when handling a large amount of input data after a previous call to the same function with a partial block. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially resulting in the execution of arbitrary code.
• An overflow condition in the ‘EVP_EncodeUpdate()’ function in ‘crypto/evp/encode.c’ is triggered when handling a large amount of input data. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially resulting in the execution of arbitrary code.
