Insight

Insight

It was discovered that Java did not correctly handle untrusted applets. If a user were tricked into running a malicious applet, a remote attacker could gain user privileges, or list directory contents. (CVE-2008-5347, CVE-2008-5350) It was discovered that Kerberos authentication and RSA public key processing were not correctly handled in Java. A remote attacker could exploit these flaws to cause a denial of service. (CVE-2008-5348, CVE-2008-5349) It was discovered that Java accepted UTF-8 encodings that might be handled incorrectly by certain applications. A remote attacker could bypass string filters, possible leading to other exploits. (CVE-2008-5351) Overflows were discovered in Java JAR processing. If a user or automated system were tricked into processing a malicious JAR file, a remote attacker could crash the application, leading to a denial of service. (CVE-2008-5352, CVE-2008-5354) It was discovered that Java calendar objects were not unserialized safely. If a user or automated system were tricked into processing a specially crafted calendar object, a remote attacker could execute arbitrary code with user privileges. (CVE-2008-5353) It was discovered that the Java image handling code could lead to memory corruption. If a user or automated system were tricked into processing a specially crafted image, a remote attacker could crash the application, leading to a denial of service. (CVE-2008-5358, CVE-2008-5359) It was discovered that temporary files created by Java had predictable names. If a user or automated system were tricked into processing a specially crafted JAR file, a remote attacker could overwrite sensitive information. (CVE-2008-5360)
