CVE-2022-28840

Arbitrary filesystem write via font parsing

Published Jun 15, 2022 · Updated Apr 23, 2025

Out-of-bounds write in Adobe Bridge 12.0.1 and earlier allows attackers to write arbitrary files after a victim opens a malicious font. Adobe identifies font parsing as the locus but has not disclosed the parsing routine, malformed field, or bounds-check failure. The CNA description instead reports code execution in the current user's context, so the two Adobe records disagree on the final impact.
