Descriptions

The IcedTea-Web plugin before 1.2.1 does not properly handle NPVariant NPStrings without NUL terminators, which allows remote attackers to cause a denial of service (crash), obtain sensitive information from memory, or execute arbitrary code via a crafted Java applet.

El complemento IcedTea-Web anterior a v1.2.1 no maneja adecuadamente los (NPVariant) (NPStrings) sin terminadores NUL, lo que permite a atacantes remotos causar una denegación de servicio (caída), obtener información sensible de la memoria, o ejecutar código arbitrario a través de un (applet) de Java manipulado.

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.
