A heap-based buffer overflow vulnerability was found in icedtea-web, a web browser plugin for running applets written in the Java programming language. If a user were tricked into opening a malicious website, an attacker could cause the plugin to crash or possibly execute arbitrary code as the user invoking the program. This problem was initially discovered by Arthur Gerkis and got assigned CVE-2012-4540 . Fixes where applied in the 1.1, 1.2 and 1.3 branches but not to the 1.4 branch.

For the stable distribution (wheezy), this problem has been fixed in version 1.4-3~deb7u2. For the unstable distribution (sid), this problem has been fixed in version 1.4-3.1. We recommend that you upgrade your icedtea-web packages.

IcedTea is a build and integration project for the OpenJDK Java Development Toolkit. IcedTea-Web contains the browser plugin and Web start components derived from it.
