Code execution via font parser out-of-bounds write
Published Mar 18, 2022 · Updated Sep 17, 2024
Out-of-bounds writing in Adobe Acrobat Reader allows attackers to execute code as the current user through a malicious font file. The font parser writes attacker-controlled font data beyond an allocated memory boundary; Adobe has not disclosed a narrower code locus. No product authentication is required, but a victim must open the crafted file; resulting code runs with that victim's privileges.
