(Pulse Secure Issues Advisory for Pulse Connect Secure) OpenSSL Multiple Bugs Let Remote Users Decrypt Data, Deny Service, Obtain Potentially Sensitive Information, and Potentially Execute Arbitrary Code
SecurityTracker Alert ID:  1035861
SecurityTracker URL:  http://securitytracker.com/id/1035861
CVE Reference:   CVE-2016-2105, CVE-2016-2106, CVE-2016-2108, CVE-2016-2109   (Links to External Site)
Date:  May 11 2016
Impact:   Denial of service via local system, Denial of service via network, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via local system, Execution of arbitrary code via network, User access via local system, User access via network
Vendor Confirmed:  Yes  

Description:   Multiple vulnerabilities were reported in OpenSSL. A remote user can decrypt data in certain cases. A remote or local user can cause denial of service conditions. A remote user can obtain potentially sensitive information on the target system. A remote or local user may be able to execute arbitrary code on the target application using OpenSSL. Pulse Connect Secure is affected.

A remote user that can conduct a man-in-the-middle attack can conduct a padding oracle attack against data encrypted with an AES CBC cipher when the target server supports AES-NI to decrypt the data [CVE-2016-2107].

[Editor's note: This vulnerability was introduced in fix for a previous vulnerability known as the Lucky 13 padding attack (CVE-2013-0169).]

Juraj Somorovsky reported this vulnerability.

A remote or local user can supply specially crafted data to trigger an overflow in the EVP_EncodeUpdate() function and cause a heap corruption and cause the target application to crash or potentially execute arbitrary code [CVE-2016-2105]. Applications that call the affected PEM_write_bio* functions may be affected.

Guido Vranken reported this vulnerability.

A remote or local user can supply specially crafted data to trigger an overflow in the EVP_EncryptUpdate() function and cause a heap corruption and cause the target application to crash or potentially execute arbitrary code [CVE-2016-2106]. Applications that call the affected function may be affected.

Guido Vranken reported this vulnerability.

A remote or local user can supply specially crafted ASN.1 data to an application that reads data from a BIO using functions such as d2i_CMS_bio() to trigger a memory allocation error and consume excessive memory on the target system [CVE-2016-2109]. TLS applications are not affected.

Brian Carpenter reported this vulnerability.

An application can supply a specially crafted ASN.1 string longer than 1024 bytes to the X509_NAME_oneline() function on EBCDIC systems to trigger a memory over-read and return arbitrary stack data containing potentially sensitive information [CVE-2016-2176].

Guido Vranken reported this vulnerability.

Impact:   A remote user can decrypt traffic in certain cases.

A remote or local user may be able to execute arbitrary code on the target application that uses OpenSSL.

A remote or local user can cause denial of service conditions on the target system.

A remote user can obtain potentially sensitive information on the target system.

Solution:   Pulse Secure has issued an advisory for CVE-2016-2105, CVE-2016-2106, CVE-2016-2108, and CVE-2016-2109 for Pulse Connect Secure (formerly Juniper Pulse Secure).

No solution was available at the time of this entry. The vendor is working on a fix.

The Pulse Secure advisory is available at:

Cause:   Access control error, Boundary error
