Security Bulletin

Summary

OpenSSL vulnerabilities were disclosed on September 22 and 26, 2016 by the 
OpenSSL Project. OpenSSL is used by IBM Tealeaf Customer Experience. IBM 
Tealeaf Customer Experience has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2016-6304

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple
memory leaks in t1_lib.c during session renegotiation. By sending an overly 
large OCSP Status Request extension, a remote attacker could exploit this 
vulnerability to consume all available memory resources.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-6305

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in SSL_peek(). By sending specially crafted data, a remote authenticated 
attacker could exploit this vulnerability to cause the service to hang.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/117111 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-2177

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the 
incorrect use of pointer arithmetic for heap-buffer boundary checks. By 
leveraging unexpected malloc behavior, a remote attacker could exploit this 
vulnerability to trigger an integer overflow and cause the application to 
crash.

CVSS Base Score: 5.9

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/113890 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-2178

DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive 
information, caused by an error in the DSA implementation that allows the 
following of a non-constant time codepath for certain operations. An attacker
could exploit this vulnerability using a cache-timing attack to recover the 
private DSA key.

CVSS Base Score: 5.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/113889 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-6307

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory
allocation error in the logic prior to the excessive message length check. By
initiating multiple connection attempts, a remote authenticated attacker could
send an overly large message to exhaust all available memory resources.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/117113 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
