USN-3735-1: OpenJDK 7 vulnerability

Releases

• Ubuntu 14.04 ESM

Packages

• openjdk-7 - Open Source Java implementation

Details

It was discovered that the PatternSyntaxException class in OpenJDK did not
properly validate arguments passed to it. An attacker could use this to
potentially construct a class that caused a denial of service (excessive
memory consumption).

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

• icedtea-7-jre-jamvm - 7u181-2.6.14-0ubuntu0.2
• openjdk-7-jdk - 7u181-2.6.14-0ubuntu0.2
• openjdk-7-jre - 7u181-2.6.14-0ubuntu0.2
• openjdk-7-jre-headless - 7u181-2.6.14-0ubuntu0.2
• openjdk-7-jre-lib - 7u181-2.6.14-0ubuntu0.2

After a standard system update you need to restart any Java
applications or applets to make all the necessary changes.
