New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
Security Fix(es) :- Multiple flaws were discovered in the RMI and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. (CVE-2017-10285, CVE-2017-10346)
- It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the sname field from the plain text part rather than encrypted part of the KDC reply message. A man-in-the- middle attacker could possibly use this flaw to impersonate Kerberos services to Java applications acting as Kerberos clients. (CVE-2017-10388)
- It was discovered that the Security component of OpenJDK generated weak password-based encryption keys used to protect private keys stored in key stores. This made it easier to perform password guessing attacks to decrypt stored keys if an attacker could gain access to a key store. (CVE-2017-10356)
- Multiple flaws were found in the Smart Card IO and Security components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2017-10274, CVE-2017-10193)
- It was found that the FtpClient implementation in the Networking component of OpenJDK did not set connect and read timeouts by default. A malicious FTP server or a man-in-the-middle attacker could use this flaw to block execution of a Java application connecting to an FTP server. (CVE-2017-10355)
- It was found that the HttpURLConnection and HttpsURLConnection classes in the Networking component of OpenJDK failed to check for newline characters embedded in URLs. An attacker able to make a Java application perform an HTTP request using an attacker provided URL could possibly inject additional headers into the request. (CVE-2017-10295)
- It was discovered that the Security component of OpenJDK could fail to properly enforce restrictions defined for processing of X.509 certificate chains. A remote attacker could possibly use this flaw to make Java accept certificate using one of the disabled algorithms.
(CVE-2017-10198)
- It was discovered that multiple classes in the JAXP, Serialization, Libraries, and JAX-WS components of OpenJDK did not limit the amount of memory allocated when creating object instances from the serialized form.
A specially crafted input could cause a Java application to use an excessive amount of memory when deserialized.
(CVE-2017-10349, CVE-2017-10357, CVE-2017-10347, CVE-2017-10281, CVE-2017-10345, CVE-2017-10348, CVE-2017-10350)
Bug Fix(es) :
- Previously, OpenJDK could not handle situations when the kernel blocked on a read even when polling the socket indicated that a read is possible. As a consequence, OpenJDK could hang indefinitely. With this update, OpenJDK polls with a timeout and performs a non-blocking read on success, and it no longer hangs in these situations.
