GLSA-200602-07 : Sun JDK/JRE: Applet privilege escalation
Medium Nessus Plugin ID 20921
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200602-07 (Sun JDK/JRE: Applet privilege escalation)
Applets executed using JRE or JDK can use 'reflection' APIs functions to elevate its privileges beyond the sandbox restrictions.
Adam Gowdiak discovered five vulnerabilities that use this method for privilege escalation. Two more vulnerabilities were discovered by the vendor. Peter Csepely discovered that Web Start Java applications also can an escalate their privileges.
A malicious Java applet can bypass Java sandbox restrictions and hence access local files, connect to arbitrary network locations and execute arbitrary code on the user's machine. Java Web Start applications are affected likewise.
Select another Java implementation using java-config.
SolutionAll Sun JDK users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-java/sun-jdk-188.8.131.52' All Sun JRE users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-java/sun-jre-bin-184.108.40.206'
