CVE-2025-55004 | ImageMagick: heap-buffer overflow read in MNG magnification with alpha

Exp

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, ImageMagick is vulnerable to heap-buffer overflow read around the handling of images with separate alpha channels when performing image magnification in ReadOneMNGIMage. This can likely be used to leak subsequent memory contents into the output image. This issue has been patched in version 7.1.2-1.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
