Mandriva Linux Security Advisory 2012-122
Posted Aug 3, 2012

Mandriva Linux Security Advisory 2012-122 - Multiple vulnerabilities has been discovered and corrected in icedtea-web. An uninitialized pointer use flaw was found in IcedTea-Web web browser plugin. A malicious web page could use this flaw make IcedTea-Web browser plugin pass invalid pointer to a web browser. Depending on the browser used, it may cause the browser to crash or possibly execute arbitrary code. It was discovered that the IcedTea-Web web browser plugin incorrectly assumed that all strings provided by browser are NUL terminated, which is not guaranteed by the NPAPI (Netscape Plugin Application Programming Interface. When used in a browser that does not NUL terminate NPVariant NPStrings, this could lead to buffer over-read or over-write, resulting in possible information leak, crash, or code execution. The updated packages have been upgraded to the 1.1.6 version which is not affected by these issues.

Ubuntu Security Notice 1521-1 - Chamal De Silva discovered that the IcedTea-Web Java web browser plugin could dereference an uninitialized pointer. A remote attacker could use this to craft a malicious web page that could cause a denial of service by crashing the web browser or possibly execute arbitrary code. Steven Bergom and others discovered that the IcedTea-Web Java web browser plugin assumed that all strings provided by browsers are NULL terminated, which is not guaranteed by the NPAPI (Netscape Plugin Application Programming Interface). A remote attacker could use this to craft a malicious Java applet that could cause a denial of service by crashing the web browser, expose sensitive information or possibly execute arbitrary code. Various other issues were also addressed.

Red Hat Security Advisory 2012-1132-01 - The IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project. It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations. An uninitialized pointer use flaw was found in the IcedTea-Web plug-in. Visiting a malicious web page could possibly cause a web browser using the IcedTea-Web plug-in to crash, disclose a portion of its memory, or execute arbitrary code. It was discovered that the IcedTea-Web plug-in incorrectly assumed all strings received from the browser were NUL terminated. When using the plug-in with a web browser that does not NUL terminate strings, visiting a web page containing a Java applet could possibly cause the browser to crash, disclose a portion of its memory, or execute arbitrary code.
