Lifecycle Timeline
2Description
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is a heap-buffer-overflow (HBO) in icAnsiToUtf8() in the XML conversion path. The issue is triggered by a crafted ICC profile which causes icAnsiToUtf8(std::string&, char const*) to treat an input buffer as a C-string and call operations that rely on strlen()/null-termination. AddressSanitizer reports an out-of-bounds READ of size 115 past a 114-byte heap allocation, with the failure observed while running the iccToXml tool. This issue has been patched in version 2.3.1.6.
Analysis
Heap buffer overflow in iccDEV's icAnsiToUtf8() function allows local attackers to cause denial of service via a crafted ICC color profile processed by the iccToXml tool. The vulnerability exists in versions prior to 2.3.1.6 and stems from unsafe string handling that treats non-null-terminated buffers as C-strings, triggering out-of-bounds memory reads. …
