- security fix
It was discovered that the Libraries component of OpenJDK accepted ECSDA
signatures using non-canonical DER encoding. This could cause a Java application
to accept signature in an incorrect format not accepted by other cryptographic
It was discovered that the Libraries component of OpenJDK did not validate the
length of the object identifier read from the DER input before allocating memory
to store the OID. An attacker able to make a Java application decode a specially
crafted DER input could cause the application to consume an excessive amount of
A covert timing channel flaw was found in the DSA implementation in the
Libraries component of OpenJDK. A remote attacker could possibly use this flaw
to extract certain information about the used key via a timing side channel.
It was discovered that the Networking component of OpenJDK failed to properly
parse user info from the URL. A remote attacker could cause a Java application
to incorrectly parse an attacker supplied URL and interpret it differently from
other applications processing the same URL.
. CVE-2017-3231, CVE-2017-3261
Multiple flaws were found in the Networking components in OpenJDK. An
untrusted Java application or applet could use these flaws to bypass certain
Java sandbox restrictions.
It was discovered that the RMI registry and DCG implementations in the RMI
component of OpenJDK performed deserialization of untrusted inputs. A remote
attacker could possibly use this flaw to execute arbitrary code with the
privileges of RMI registry or a Java RMI application.
It was discovered that the JAAS component of OpenJDK did not use the correct
way to extract user DN from the result of the user search LDAP query. A
specially crafted user LDAP entry could cause the application to use an
It was discovered that the 2D component of OpenJDK performed parsing of iTXt
and zTXt PNG image chunks even when configured to ignore metadata. An attacker
able to make a Java application parse a specially crafted PNG image could cause
the application to consume an excessive amount of memory.
. CVE-2017-3272, CVE-2017-3289
Multiple flaws were discovered in the Libraries and Hotspot components in
OpenJDK. An untrusted Java application or applet could use these flaws to
completely bypass Java sandbox restrictions.
A flaw was found in the way the DES/3DES cipher was used as part of the
TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover
some plaintext data by capturing large amounts of encrypted traffic between
TLS/SSL server and client if the communication used a DES/3DES based
