The BMP image parser in Sun Java Development Kit (JDK) before 1.5.0_11-b03 and 1.6.x before 1.6.0_01-b06, and Sun Java Runtime Environment in JDK and JRE 6, JDK and JRE 5.0 Update 10 and earlier, SDK and JRE 1.4.2_14 and earlier, and SDK and JRE 1.3.1_19 and earlier, when running on Unix/Linux systems, allows remote attackers to cause a denial of service (JVM hang) via untrusted applets or applications that open arbitrary local files via a crafted BMP file, such as /dev/tty.

Sun Java JRE 1.1.x through 1.4.x writes temporary files with long filenames that become predictable on a file system that uses 8.3 style short names, which allows remote attackers to write arbitrary files to known locations and facilitates the exploitation of vulnerabilities in applications that rely on unpredictable file names.
