1) Buffer overflow (CVE-ID: CVE-2018-12932)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

2) Out-of-bounds write (CVE-ID: CVE-2018-12933)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
PlayEnhMetaFileRecord in enhmetafile.c in Wine 3.7 allows attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact because the attacker controls the pCreatePen->ihPen array index.
