Mageia Bugzilla – Bug 9029
java-1.7.0-openjdk new security issues fixed in IcedTea 2.3.6
Last modified: 2013-02-17 01:57:36 CET
RedHat and Fedora have issued advisories on February 8 and 9:
We need to sync the appropriate changes from Fedora and issue an update.
The CVEs fixed in IceaTea 1.3.5 are the same as were in IcedTea6, plus:
CVE-2013-0431 and CVE-2013-0444
The upstream release announcements haven't been issued yet.
Turns out 2.3.5 wasn't announced because of regressions.
2.3.6 has been released, and announced:
Finally, the upstream blog post has been posted:
Now we just need Fedora to finish their update so we can finish ours.
Updated package uploaded for Cauldron. Thanks D Morgan!
Updated package uploaded for Mageia 2.
Updated java-1.7.0-openjdk packages fix security vulnerabilities:
Multiple improper permission check issues were discovered in the AWT,
CORBA, JMX, Libraries, and Beans components in OpenJDK. An untrusted Java
application or applet could use these flaws to bypass Java sandbox
restrictions (CVE-2013-0442, CVE-2013-0445, CVE-2013-0441, CVE-2013-1475,
CVE-2013-1476, CVE-2013-0429, CVE-2013-0450, CVE-2013-0425, CVE-2013-0426,
Multiple flaws were found in the way image parsers in the 2D and AWT
components handled image raster parameters. A specially-crafted image could
cause Java Virtual Machine memory corruption and, possibly, lead to
arbitrary code execution with the virtual machine privileges
A flaw was found in the AWT component's clipboard handling code. An
untrusted Java application or applet could use this flaw to access
clipboard data, bypassing Java sandbox restrictions (CVE-2013-0432).
The default Java security properties configuration did not restrict access
to certain com.sun.xml.internal packages. An untrusted Java application or
applet could use this flaw to access information, bypassing certain Java
sandbox restrictions. This update lists the whole package as restricted
Multiple improper permission check issues were discovered in the JMX,
Libraries, Networking, and JAXP components. An untrusted Java application
or applet could use these flaws to bypass certain Java sandbox
restrictions (CVE-2013-0431, CVE-2013-0427, CVE-2013-0433, CVE-2013-0434).
It was discovered that the RMI component's CGIHandler class used user
inputs in error messages without any sanitization. An attacker could use
this flaw to perform a cross-site scripting (XSS) attack (CVE-2013-0424).
It was discovered that the SSL/TLS implementation in the JSSE component
did not properly enforce handshake message ordering, allowing an unlimited
number of handshake restarts. A remote attacker could use this flaw to
make an SSL/TLS server using JSSE consume an excessive amount of CPU by
continuously restarting the handshake (CVE-2013-0440).
It was discovered that the JSSE component did not properly validate
Diffie-Hellman public keys. An SSL/TLS client could possibly use this flaw
to perform a small subgroup attack (CVE-2013-0443).
IcedTea has been updated to version 2.3.6, which fixes these issues.
Updated packages in core/updates_testing:
Could not find PoC for any of the listed fixes.
Installed and checked version. OK
Tested with HelloWorld and OddEven, both worked normally

Ensured java-1.7.0-openjdk is being used.
# update-alternatives --config java
There are 3 programs which provide `java'.

Using `/usr/lib/jvm/jre-1.7.0-openjdk/bin/java' to provide `java'.
Tested using Bill's examples.
