Synopsis
A programming platform installed on the remote Windows host is affected by multiple vulnerabilities.
Description
The version of Oracle JRockit installed on the remote Windows host is R28 prior to R28.3.9. It is, therefore, affected by multiple vulnerabilities :
- An unspecified flaw exists in the Security subcomponent due to a failure to reject MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange messages.
A man-in-the-middle attacker, by triggering collisions, can exploit this issue to spoof servers. (CVE-2015-7575)
- A memory corruption issue exists in the AWT subcomponent when decoding JPEG files. A remote attacker can exploit this to execute arbitrary code. (CVE-2016-0483)
- A collision-based forgery vulnerability, known as SLOTH (Security Losses from Obsolete and Truncated Transcript Hashes), exists in the TLS protocol due to accepting RSA-MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange messages during a TLS handshake. A man-in-the-middle attacker can exploit this, via a transcript collision attack, to impersonate a TLS server. (CVE-2015-7575) (CVE-2016-0475)
- A denial of service vulnerability exists in the JAXP subcomponent during the handling of expanded general entities. A remote attacker can exploit this to bypass the 'totalEntitySizeLimit' restrictions and exhaust available memory. (CVE-2016-0466)
Solution
Upgrade to Oracle JRockit version R28.3.9 or later as referenced in the January 2016 Oracle Critical Patch Update advisory.
