ZDI-08-043: Sun Java Web Start vm args Stack Buffer Overflow http://www.zerodayinitiative.com/advisories/ZDI-08-043 July 17, 2008
-- Affected Vendors: Sun Microsystems -- Affected Products: Sun Microsystems Java Runtime -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 6013. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Sun Java Web Start. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the GetVMArgsOption() function used while parsing the java-vm-args attribute of the j2se tag in xml based JNLP files. When a user downloads a malicious JNLP file, the vulnerable attribute is read into a static buffer. If an overly long value is defined by the java-vm-args attribute, a stack based buffer overflow occurs, resulting in an exploitable condition. -- Vendor Response: Sun Microsystems has issued an update to correct this vulnerability.
