CVE-2009-1099: Integer signedness error in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17...

Integer signedness error in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier, and 6 Update 12 and earlier, allows remote attackers to access files or execute arbitrary code via crafted glyph descriptions in a Type1 font, which bypasses a signed comparison and triggers a buffer overflow.

Security readout for executives and security teams

Old Java runtimes can mishandle specially crafted Type1 font data. If an affected JDK or JRE processes the malicious font, a remote attacker may access files or run code. The source bundle does not show active exploitation, but the impact is serious for legacy Java estates. Exposure is concentrated in legacy Java SE 5.0 and 6 installations, including systems using vendor-packaged or bundled Java referenced by SUSE, HP, Red Hat, Gentoo, VMware, and Avaya advisories. Exact downstream product impact is not fully detailed in the bundle. Handle as a legacy-risk cleanup item with high impact. It is not KEV-listed in the bundle, but affected Java versions are obsolete and can permit code execution if exposed to malicious font content. Mitigation focus: Inventory Java JDK/JRE versions across endpoints, servers, and bundled application runtimes.; Prioritize removal or vendor-supported updating of Java 5.0 Update 17 and earlier.; Prioritize removal or vendor-supported updating of Java 6 Update 12 and earlier..
