Gentoo Linux Security Advisory

Title: Sun and Blackdown Java: Applet privilege escalation (GLSA 200506-14)
Severity: normal
Exploitable: remote
Date: June 19, 2005
Bug(s): #96092, #96229
ID: 200506-14

Synopsis

Sun's and Blackdown's JDK or JRE may allow untrusted applets to elevate their privileges.

Background

Sun and Blackdown both provide implementations of the Java Development Kit (JDK) and Java Runtime Environment (JRE).

Affected Packages

Package: dev-java/sun-jdk
Vulnerable: < 1.4.2.08
Unaffected: >= 1.4.2.08
Architectures: All supported architectures

Package: dev-java/sun-jre-bin
Vulnerable: < 1.4.2.08
Unaffected: >= 1.4.2.08
Architectures: All supported architectures

Package: dev-java/blackdown-jdk
Vulnerable: < 1.4.2.02
Unaffected: >= 1.4.2.02
Architectures: All supported architectures

Package: dev-java/blackdown-jre
Vulnerable: < 1.4.2.02
Unaffected: >= 1.4.2.02
Architectures: All supported architectures


Description

Both Sun's and Blackdown's JDK and JRE may allow untrusted applets to elevate privileges.

Impact

A remote attacker could embed a malicious Java applet in a web page and entice a victim to view it. This applet can then bypass security restrictions and execute any command or access any file with the rights of the user running the web browser.

Workaround

There are no known workarounds at this time.

Resolution

All Sun JDK users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.08"
All Sun JRE users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.08"
All Blackdown JDK users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jdk-1.4.2.02"
All Blackdown JRE users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jre-1.4.2.02"
Note to SPARC users: There is no stable secure Blackdown Java for the SPARC architecture. Affected users should remove the package until a SPARC package is released.
