漏洞信息
The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.
An untrusted library search path flaw was found in the JCE component of OpenJDK. A local attacker could possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and hence escalate their privileges. (CVE-2017-3511)
It was found that the JAXP component of OpenJDK failed to correctly enforce parse tree size limits when parsing XML document. An attacker able to make a Java application parse a specially crafted XML document could use this flaw to make it consume an excessive amount of CPU and memory. (CVE-2017-3526)
It was discovered that the HTTP client implementation in the Networking component of OpenJDK could cache and re-use an NTLM authenticated connection in a different security context. A remote attacker could possibly use this flaw to make a Java application perform HTTP requests authenticated with credentials of a different user. (CVE-2017-3509)
