CVE-2026-30983Public exploit

Stack corruption via unterminated named-color strings

Published Mar 10, 2026 · Updated Mar 10, 2026

Stack buffer overflow in iccDEV before 2.3.1.5 allows local users to corrupt stack memory or crash iccToXml with a crafted ICC profile. The named-color parser fills fixed-size prefix and suffix arrays without NUL termination, and icFixXml passes them to strcpy, overrunning a 256-byte stack buffer. Processing the attacker-supplied profile requires user interaction; the demonstrated result is an AddressSanitizer-detected crash.
