Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

tificc in Little CMS 2.9 has an out-of-bounds write in the cmsPipelineCheckAndRetreiveStages function in cmslut.c in liblcms2.a via a crafted TIFF file. NOTE: Little CMS developers do consider this a vulnerability because the issue is based on an sample program using LIBTIFF and do not apply to the lcms2 library, lcms2 does not depends on LIBTIFF other than to build sample programs, and the issue cannot be reproduced on the lcms2 library.”
