CVE-2024-49533Public exploit

Memory disclosure via unchecked font table bounds

Published Dec 10, 2024 · Updated Dec 11, 2024

Out-of-bounds read in Adobe Acrobat Reader allows attackers to disclose process memory through a malicious PDF with an embedded font. The gvar parser fails to ensure a GlyphVariationData table is large enough for the declared per-tuple private-point-number data before reading it. Exploitation requires a user to open the crafted PDF; the resulting memory disclosure can expose sensitive process data and aid mitigation bypass.
