What it is

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile and TIFF input can trigger a heap-buffer-overflow (HBO) in CTiffImg::WriteLine(). The issue is observable under AddressSanitizer as an out-of-bounds heap read when running iccSpecSepToTiff on a malicious .icc + .tif pair, leading to a crash during TIFF strip writing. This issue has been patched in version 2.3.1.6.
