Title
RealTerm Serial Terminal 2.0.0.70 SEH Overflow Crash
Summary
RealTerm Serial Terminal 2.0.0.70 contains a stack-based buffer overflow vulnerability in the Echo Port field that allows local attackers to crash the application by triggering a structured exception handler (SEH) chain corruption. Attackers can craft a malicious input string with 268 bytes of padding followed by SEH overwrite values and paste it into the Port field to cause denial of service.

Title
RealTerm Serial Terminal 2.0.0.70 Buffer Overflow SEH
Summary
RealTerm Serial Terminal 2.0.0.70 contains a structured exception handling (SEH) buffer overflow vulnerability in the Echo Port tab that allows local attackers to execute arbitrary code by supplying a malicious payload. Attackers can craft a buffer overflow payload with a POP POP RET gadget chain and shellcode that triggers code execution when pasted into the Port field and the Change button is clicked.

Title
RealTerm Serial Terminal 2.0.0.70 SEH Overflow Crash
Summary
RealTerm Serial Terminal 2.0.0.70 contains a stack-based buffer overflow vulnerability in the Echo Port field that allows local attackers to crash the application by triggering a structured exception handler (SEH) chain corruption. Attackers can craft a malicious input string with 268 bytes of padding followed by SEH overwrite values and paste it into the Port field to cause denial of service.
