libgc integer overflows
SecurityVulns ID:12549
Threat Level:
Description:Multiple integer overflows in malloc / calloc implementations.
Affected:LIBGC : libgc 7.1
CVE:CVE-2012-2673 (Multiple integer overflows in the (1) GC_generic_malloc and (2) calloc funtions in malloc.c, and the (3) GC_generic_malloc_ignore_off_page function in mallocx.c in Boehm-Demers-Weiser GC (libgc) before 7.2 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.)

Java environment limitations bypass
updated since 29.08.2012
SecurityVulns ID:12548
Threat Level:
Description:There are few ways to bypass limitations and execute privileged code from the applet.
Affected:ORACLE : JDK 7
CVE:CVE-2012-4681 (Multiple vulnerabilities in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 6 and earlier allow remote attackers to execute arbitrary code via a crafted applet that bypasses SecurityManager restrictions by (1) using com.sun.beans.finder.ClassFinder.findClass and leveraging an exception with the forName method to access restricted classes from arbitrary packages such as sun.awt.SunToolkit, then (2) using "reflection with a trusted immediate caller" to leverage the getField method to access and modify private fields, as exploited in the wild in August 2012 using Gondzz.class and Gondvv.class.)
