Description

This security bulletin contains information about 2 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2018-12932)

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 (heap-based buffer overflow) or possibly have unspecified other impact by triggering a large pAlphaBlend->cbBitsSrc value.


2) Out-of-bounds write (CVE-ID: CVE-2018-12933)

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.
