SUMMARY

Blue Coat products using affected versions of OpenSSL are susceptible to multiple vulnerabilities.  A remote attacker can exploit these vulnerabilities to intercept and decrypt TLS sessions, obtain arbitrary data from the target's memory stack, or execute arbitrary code through buffer underflow and overflow.  The attacker can also cause denial of service through memory corruption and depletion.

ADDITIONAL PRODUCT INFORMATION

Blue Coat products may act as both client and server in SSL/TLS connections, and may use application functionality for cryptographic operations.  Blue Coat products act as a client when connecting to Blue Coat services such as WebPulse, DRTR, and licensing and subscription services.  Products should be considered vulnerable in all interfaces that provide SSL/TLS connections for data and management interfaces unless the CVE is specific to SSL/TLS client or server functionality (as noted in the descriptions above) or unless otherwise stated below:

  • CacheFlow: All CVEs affect only management connections.
  • ProxySG: CVE-2016-2109 affects only management connections.

Blue Coat products that use a native installation of OpenSSL but do not install or maintain that implementation are not vulnerable to any of these CVEs.  However, the underlying platform or application that installs and maintains OpenSSL may be vulnerable.  Blue Coat urges our customers to update the versions of OpenSSL that are natively installed for Client Connector for OS X, Proxy Client for OS X, and Reporter 9.x for Linux.

Some Blue Coat products do not enable or use all functionality within OpenSSL.  The products listed below do not utilize the functionality described in the CVEs below and are thus not known to be vulnerable to them.  However, fixes for these CVEs will be included in the patches that are provided.

  • CacheFlow: CVE-2016-2105, CVE-2016-2106, and CVE-2016-2107
  • MAA: CVE-2016-2106 and CVE-2016-2109
  • MC: CVE-2016-2107
  • PacketShaper: CVE-2016-2105
  • PacketShaper S-Series: CVE-2016-2105 and CVE-2016-2109
  • PolicyCenter: CVE-2016-2105
  • PolicyCenter S-Series: CVE-2016-2105 and CVE-2016-2109
  • ProxyAV: CVE-2016-2107
  • ProxySG: CVE-2016-2105 and CVE-2016-2106

Some Blue Coat hardware platforms do not support the AESNI instruction set in their CPU architectures.  The products and hardware platforms listed below do not support AESNI, do not use the AESNI-based AES implementation in OpenSSL, and are thus not vulnerable to CVE-2016-2107.  However, a fix for this CVE will be included in the software patches that are provided.

  • ICSP: AFL2-12A-D525, customer-provided hardware platforms that do not support AESNI
  • NNP: customer-provided hardware platforms that do not support AESNI
  • NSP: customer-provided hardware platforms that do not support AESNI
  • ProxySG: SG300, SG600, SG900, SG9000
  • Security Analytics: customer-provided hardware platforms that do not support AESNI
  • SSLV: SV1800
  • XOS: APM-8650, CPM-8600, CPM-9600

ISSUES

CVE-2016-2105
Severity / CVSSv2 Medium / 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)
References SecurityFocus: BID 89757 / NVD: CVE-2016-2105
Impact Denial of service, code execution
Description A flaw in the Base64 encoding module allows a remote attacker to supply large input data and trigger a heap overflow, resulting in denial of service and possibly arbitrary code execution.

 

CVE-2016-2106
Severity / CVSSv2 Medium / 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)
References SecurityFocus: BID 89744 / NVD: CVE-2016-2106
Impact Denial of service, code execution
Description A flaw in the generic symmetric encryption/decryption module allows a remote attacker to supply large input data and trigger a heap overflow, resulting in denial of service and possibly arbitrary code execution.

 

CVE-2016-2107
Severity / CVSSv2 Low / 2.6 (AV:N/AC:H/Au:N/C:P/I:N/A:N)
References SecurityFocus: BID 89760 / NVD: CVE-2016-2107
Impact Information disclosure
Description A flaw introduced as part of the fix for CVE-2013-0169 (Lucky13) allows a remote man-in-the-middle (MITM) attacker to perform a padding oracle attack and decrypt intercepted TLS traffic when the TLS sessions use AES CBC cipher suites and the server supports AESNI.  The CVSS v2 score for CVE-2016-2107 listed in this Security Advisory is published by the National Vulnerability Database (NVD).  The effective CVSS v2 score my be higher for Blue Coat products if the decrypted plaintext contains cookie or password information.

 

CVE-2016-2108
Severity / CVSSv2 High / 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
References SecurityFocus: BID 89752 / NVD: CVE-2016-2108
Impact Denial of service, code execution
Description A flaw in the ASN.1 encoder allows a remote attacker to send a crafted X.509 certificate and trigger a buffer underflow on the target if it parses and re-encodes the certificate.  Parsing and re-encoding occurs only if the target successfully verifies that certificate signature.  Exploiting this vulnerability can result in denial of service through memory corruption and possible arbitrary code execution.

 

CVE-2016-2109
Severity / CVSSv2 High / 7.8 (AV:N/AC:L/Au:N/C:N/I:N/A:C)
References SecurityFocus: BID 87940 / NVD: CVE-2016-2109
Impact Denial of service
Description A flaw in the ASN.1 decoder allows a remote attacker to send crafted ASN.1 data and trigger excessive memory allocation on the target.  This can result in denial of service through memory depletion.

 

CVE-2016-2176
Severity / CVSSv2 Medium / 6.4 (AV:N/AC:L/Au:N/C:P/I:N/A:P)
References SecurityFocus: BID 89746 / NVD: CVE-2016-2176
Impact Information disclosure
Description An overread flaw in X.509 certificate ASN.1 string parsing on EBCDIC systems allows a remote attacker to send crafted X.509 certificates and obtain arbitrary data from the target's memory stack.

 

MITIGATION

These vulnerabilities can be exploited in CacheFlow only through the management interface.  Allowing only machines, IP addresses and subnets from a trusted network to access the CacheFlow management interface reduces the threat of exploiting the vulnerabilities.
