Information disclosure via EMF out-of-bounds reads
Published Apr 15, 2020 · Updated Aug 4, 2024
Out-of-bounds reads in the Windows Graphics Component allow attackers to disclose memory through crafted EMF images. The gdi32full.dll and mf3216.dll EMF handlers read past allocated buffers when processing crafted EMR_SETDIBITSTODEVICE records. Exploitation requires a user to visit a malicious page or open a malicious file; disclosed uninitialized memory can aid further compromise.
