Description OSIDB Bzimport 2026-03-28 13:02:51 UTC 
Bochs 2.6-5 contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by supplying an oversized input string to the application. Attackers can craft a malicious payload with 1200 bytes of padding followed by a return-oriented programming chain to overwrite the instruction pointer and execute shell commands with application privileges.
