Details

It was discovered that the Smart Card IO subsystem in OpenJDK did not
properly maintain state. An attacker could use this to specially construct
an untrusted Java application or applet to gain access to a smart card,
bypassing sandbox restrictions. (CVE-2017-10274)

Gaston Traberg discovered that the Serialization component of OpenJDK did
not properly limit the amount of memory allocated when performing
deserializations. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2017-10281)

It was discovered that the Remote Method Invocation (RMI) component in
OpenJDK did not properly handle unreferenced objects. An attacker could use
this to specially construct an untrusted Java application or applet that
could escape sandbox restrictions. (CVE-2017-10285)

It was discovered that the HTTPUrlConnection classes in OpenJDK did not
properly handle newlines. An attacker could use this to convince a Java
application or applet to inject headers into http requests.
(CVE-2017-10295)

Francesco Palmarini, Marco Squarcina, Mauro Tempesta, and Riccardo Focardi
discovered that the Serialization component of OpenJDK did not properly
restrict the amount of memory allocated when deserializing objects from
Java Cryptography Extension KeyStore (JCEKS). An attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2017-10345)

It was discovered that the Hotspot component of OpenJDK did not properly
perform loader checks when handling the invokespecial JVM instruction. An
attacker could use this to specially construct an untrusted Java
application or applet that could escape sandbox restrictions.
(CVE-2017-10346)

Gaston Traberg discovered that the Serialization component of OpenJDK did
not properly limit the amount of memory allocated when performing
deserializations in the SimpleTimeZone class. An attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2017-10347)

It was discovered that the Serialization component of OpenJDK did not
properly limit the amount of memory allocated when performing
deserializations. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2017-10348, CVE-2017-10357)

It was discovered that the JAXP component in OpenJDK did not properly limit
the amount of memory allocated when performing deserializations. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2017-10349)

It was discovered that the JAX-WS component in OpenJDK did not properly
limit the amount of memory allocated when performing deserializations. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2017-10350)

It was discovered that the Networking component of OpenJDK did not properly
set timeouts on FTP client actions. A remote attacker could use this to
cause a denial of service (application hang). (CVE-2017-10355)

Francesco Palmarini, Marco Squarcina, Mauro Tempesta, Riccardo Focardi, and
Tobias Ospelt discovered that the Security component in OpenJDK did not
sufficiently protect password-based encryption keys in key stores. An
attacker could use this to expose sensitive information. (CVE-2017-10356)

Jeffrey Altman discovered that the Kerberos client implementation in
OpenJDK incorrectly trusted unauthenticated portions of Kerberos tickets. A
remote attacker could use this to impersonate trusted network services or
perform other attacks. (CVE-2017-10388)
