Multiple vulnerabilities have been reported in the Sun Java
implementation. Please review the CVE identifiers referenced below and
the associated Sun Alerts for details.
Impact
A remote attacker could entice a user to open a specially crafted JAR
archive, applet, or Java Web Start application, possibly resulting in
the execution of arbitrary code with the privileges of the user running
the application. Furthermore, a remote attacker could cause a Denial of
Service affecting multiple services via several vectors, disclose
information and memory contents, write or execute local files, conduct
session hijacking attacks via GIFAR files, steal cookies, bypass the
same-origin policy, load untrusted JAR files, establish network
connections to arbitrary hosts and posts via several vectors, modify
the list of supported graphics configurations, bypass HMAC-based
authentication systems, escalate privileges via several vectors and
cause applet code to be executed with older, possibly vulnerable
versions of the JRE.
NOTE: Some vulnerabilities require a trusted environment, user
interaction, a DNS Man-in-the-Middle or Cross-Site-Scripting attack.
Workaround
There is no known workaround at this time.
Resolution
All Sun JRE 1.5.x users should upgrade to the latest version:
Gentoo is ceasing support for the 1.4 generation of the Sun Java
Platform in accordance with upstream. All 1.4 JRE and JDK versions are
masked and will be removed shortly.
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at https://bugs.gentoo.org.
