Description

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.

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
