Summary

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.

Common Weakness Enumeration (CWE)

CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Common Attack Pattern Enumeration and Classification (CAPEC)

Buffer Overflow via Environment Variables
This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
Overflow Buffers
Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
Client-side Injection-induced Buffer Overflow
This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
Filter Failure through Buffer Overflow
In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
MIME Conversion
An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

description	According to its self-reported version, the Cisco TelePresence Video Communication Server (VCS) / Expressway running on the remote host is 8.x prior to 8.8. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic. (CVE-2015-2808) - A flaw exists in the web framework of TelePresence Video Communication Server (VCS) Expressway due to missing authorization checks on certain administrative pages. An authenticated, remote attacker can exploit this to bypass read-only restrictions and install Tandberg Linux Packages (TLPs) without proper authorization. (CVE-2015-6413) - A flaw exists in certificate management and validation for the Mobile and Remote Access (MRA) component due to improper input validation of a trusted certificate. An unauthenticated, remote attacker can exploit this, using a trusted certificate, to bypass authentication and gain access to internal HTTP system resources. (CVE-2016-1444) - 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) - 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. (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. (CVE-2016-2109) - An out-of-bounds read error exists in the X509_NAME_oneline() function within file crypto/x509/x509_obj.c when handling very long ASN.1 strings. An unauthenticated, remote attacker can exploit this to disclose the contents of stack memory. (CVE-2016-2176) - An information disclosure vulnerability exists in the file system permissions due to certain files having overly permissive permissions. An unauthenticated, local attacker can exploit this to disclose sensitive information. (Cisco bug ID CSCuw55636) Note that Cisco bug ID CSCuw55636 and CVE-2015-6413 only affect versions 8.6.x prior to 8.8.

NASL family	Debian Local Security Checks
NASL id	DEBIAN_DLA-456.NASL
description	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. Additional information about these issues can be found in the OpenSSL security advisory at https://www.openssl.org/news/secadv/20160503.txt NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
