Description

It was discovered that the XML HMAC signature system did not correctly check certain lengths. If an attacker sent a truncated HMAC, it could bypass authentication, leading to potential privilege escalation. (CVE-2009-0217)

It was discovered that JAR bundles would appear signed if only one element was signed. If a user were tricked into running a malicious Java applet, a remote attacker could exploit this to gain access to private information and potentially run untrusted code. (CVE-2009-1896)

It was discovered that certain variables could leak information. If a user were tricked into running a malicious Java applet, a remote attacker could exploit this to gain access to private information and potentially run untrusted code. (CVE-2009-2475, CVE-2009-2690)

A flaw was discovered the OpenType checking. If a user were tricked into running a malicious Java applet, a remote attacker could bypass access restrictions. (CVE-2009-2476)

It was discovered that the XML processor did not correctly check recursion. If a user or automated system were tricked into processing a specially crafted XML, the system could crash, leading to a denial of service. (CVE-2009-2625)

It was discovered that the Java audio subsystem did not correctly validate certain parameters. If a user were tricked into running an untrusted applet, a remote attacker could read system properties. (CVE-2009-2670)

Multiple flaws were discovered in the proxy subsystem. If a user were tricked into running an untrusted applet, a remote attacker could discover local user names, obtain access to sensitive information, or bypass socket restrictions, leading to a loss of privacy. (CVE-2009-2671, CVE-2009-2672, CVE-2009-2673)

Flaws were discovered in the handling of JPEG images, Unpack200 archives, and JDK13Services. If a user were tricked into running an untrusted applet, a remote attacker could load a specially crafted file that would bypass local file access protections and run arbitrary code with user privileges. (CVE-2009-2674, CVE-2009-2675, CVE-2009-2676, CVE-2009-2689)
