CVE-2015-4844: Buffer Overflow
It was discovered that ICU Layout Engine was missing multiple boundary and error return checks. These could lead to buffer overflows and memory corruption. A specially crafted font file could cause an application using ICU to parse untrusted fonts to crash and, possibly, execute arbitrary code.
ICU code is embedded the 2D component in OpenJDK and used by FontManager. An untrusted Java application or applet could use this flaw to execute arbitrary code with Java Virtual Machine privileges and bypass Java sandbox restrictions.
Other sources
Unspecified vulnerability in Oracle Java SE 6u101, 7u85, and 8u60, and Java SE Embedded 8u51, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D.
