| CVE-2017-8284 | 1 Qemu | 1 Qemu | 2025-04-20 | N/A |
| The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail.
