CVE History

CVEPublishedCVSS v3CVSS v2
7.8 HIGH6.8 MEDIUM

Unicorn Engine v1.0.3 was discovered to contain a use-after-free vulnerability via the hook function.

7.5 HIGH5 MEDIUM

Unicorn Engine v2.0.0-rc7 and below was discovered to contain a memory leak via the function uc_close at /my/unicorn/uc.c.

7.5 HIGH5 MEDIUM

Unicorn Engine v2.0.0-rc7 and below was discovered to contain a NULL pointer dereference via qemu_ram_free.

7.5 HIGH5 MEDIUM

Unicorn Engine v2.0.0-rc7 contains memory leaks caused by an incomplete unicorn engine initialization.

8.1 HIGH6.9 MEDIUM

An issue was discovered in split_region in uc.c in Unicorn Engine before 2.0.0-rc5. It allows local attackers to escape the sandbox. An attacker must first obtain the ability to execute crafted code in the target sandbox in order to exploit this vulnerability. The specific flaw exists within the virtual memory manager. The issue results from the faulty comparison of GVA and GPA while calling uc_mem_map_ptr to free part of a claimed memory block. An attacker can leverage this vulnerability to escape the sandbox and execute arbitrary code on the host machine.

5.5 MEDIUM4.3 MEDIUM

Unicorn Engine 1.0.2 has an out-of-bounds write in tb_flush_armeb (called from cpu_arm_exec_armeb and tcg_cpu_exec_armeb).
