CVE-2023-46602Public exploitNetwork attack vector

Application crash via unchecked XML string copy

Published Oct 23, 2023 · Updated Sep 17, 2024

Stack-based buffer overflow in International Color Consortium DemoIccMAX 79ecb74 allows attackers to crash iccToXml via a crafted ICC profile. The icFixXml function copies each byte from an oversized XML string into the caller's fixed 256-byte fix stack buffer without checking the destination bounds. A user must process the profile with iccToXml; the demonstrated consequence is an out-of-bounds write followed by an application crash.
