AIX Java Advisory : java_jan2017_advisory.asc (January 2017 CPU) (SWEET32)
High Nessus Plugin ID 103190
Synopsis
The version of Java SDK installed on the remote AIX host is affected by multiple vulnerabilities.
Description
The version of Java SDK installed on the remote AIX host is affected by multiple vulnerabilities in the following subcomponents :
- A vulnerability exists in the Libraries subcomponent, known as SWEET32, in the 3DES and Blowfish algorithms due to the use of weak 64-bit block ciphers by default.
A man-in-the-middle attacker who has sufficient resources can exploit this vulnerability, via a 'birthday' attack, to detect a collision that leaks the XOR between the fixed secret and a known plaintext, allowing the disclosure of the secret text, such as secure HTTPS cookies, and possibly resulting in the hijacking of an authenticated session. (CVE-2016-2183)
- An unspecified flaw exists in the Libraries subcomponent that allows an unauthenticated, remote attacker to impact integrity. (CVE-2016-5546)
- An unspecified flaw exists in the Libraries subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition. (CVE-2016-5547)
- Multiple unspecified flaws exist in the Libraries subcomponent that allow an unauthenticated, remote attacker to disclose sensitive information.
(CVE-2016-5548, CVE-2016-5549)
- An unspecified flaw exists in the Networking subcomponent that allows an unauthenticated, remote attacker to impact integrity. (CVE-2016-5552)
- Multiple unspecified flaws exist in the Networking subcomponent that allow an unauthenticated, remote attacker to disclose sensitive information.
(CVE-2017-3231, CVE-2017-3261)
- An unspecified flaw exists in the RMI subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-3241)
- An unspecified flaw exists in the JAAS subcomponent that allows an unauthenticated, remote attacker to impact integrity. (CVE-2017-3252)
- An unspecified flaw exists in the 2D subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition. (CVE-2017-3253)
- An unspecified flaw exists in the Deployment subcomponent that allows an unauthenticated, remote attacker to disclose sensitive information.
(CVE-2017-3259)
- An unspecified flaw exists in the AWT subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-3260)
- An unspecified flaw exists in the Libraries subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-3272)
- An unspecified flaw exists in the Hotspot subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-3289)
Note that CVE-2017-3241 can only be exploited by supplying data to APIs in the specified component without using untrusted Java Web Start applications or untrusted Java applets, such as through a web service.
Note that CVE-2016-2183, CVE-2016-5546, CVE-2016-5547, CVE-2016-5552, CVE-2017-3252, and CVE-2017-3253 can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. They can also be exploited by supplying data to APIs in the specified component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service.
Solution
Fixes are available by version and can be downloaded from the IBM AIX website.
