USN-3275-2: OpenJDK 7 vulnerabilities
15 May 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Several security issues were fixed in OpenJDK 7.
- openjdk-7 - Open Source Java implementation
USN-3275-1 fixed vulnerabilities in OpenJDK 8. This update provides the corresponding updates for OpenJDK 7.
Original advisory details:
It was discovered that OpenJDK improperly re-used cached NTLM connections in some situations. A remote attacker could possibly use this to cause a Java application to perform actions with the credentials of a different user. (CVE-2017-3509)
It was discovered that an untrusted library search path flaw existed in the Java Cryptography Extension (JCE) component of OpenJDK. A local attacker could possibly use this to gain the privileges of a Java application. (CVE-2017-3511)
It was discovered that the Java API for XML Processing (JAXP) component in OpenJDK did not properly enforce size limits when parsing XML documents. An attacker could use this to cause a denial of service (processor and memory consumption). (CVE-2017-3526)
It was discovered that the FTP client implementation in OpenJDK did not properly sanitize user inputs. If a user was tricked into opening a specially crafted FTP URL, a remote attacker could use this to manipulate the FTP connection. (CVE-2017-3533)
It was discovered that OpenJDK allowed MD5 to be used as an algorithm for JAR integrity verification. An attacker could possibly use this to modify the contents of a JAR file without detection. (CVE-2017-3539)
It was discovered that the SMTP client implementation in OpenJDK did not properly sanitize sender and recipient addresses. A remote attacker could use this to specially craft email addresses and gain control of a Java application’s SMTP connections. (CVE-2017-3544)
