Related bugreports: #159547


Multiple unspecified vulnerabilities have been identified in Sun Java Development Kit (JDK) and Sun Java Runtime Environment (JRE).

2.  Impact Information


The Sun Java Development Kit (JDK) and the Sun Java Runtime Environment (JRE) provide the Sun Java platform. The x86 emulation Sun's J2SE Development Kit for AMD64 contains a vulnerable version of Sun's JDK.


Chris Evans has discovered multiple buffer overflows in Sun JDK and Sun JRE possibly related to various AWT or font layout functions. Tom Hawtin has discovered an unspecified vulnerability in Sun JDK and Sun JRE relating to unintended applet data access. He has also discovered multiple other unspecified vulnerabilities in Sun JDK and Sun JRE allowing unintended Java applet or application resource acquisition. Additionally, a memory corruption error has been found in the handling of GIF images with zero width field blocks.


An attacker could entice a user to run a specially crafted Java applet or application that could read, write, or execute local files with the privileges of the user running the JVM, access data maintained in other Java applets, or escalate the privileges of the currently running Java applet or application allowing for unauthorized access to system resources.

3.  Resolution Information


There is no known workaround at this time.


All AMD64 x86 emulation Sun's J2SE Development Kit users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-java-"
