Description

iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. Versions 2.3.1.1 and below have Undefined Behavior in CIccTagXmlSegmentedCurve::ToXml(). This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and Code Execution. This issue has been fixed in version 2.3.1.2.

• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
• CWE-476NULL Pointer DereferenceThe product dereferences a pointer that it expects to be valid but is NULL.
• CWE-690Unchecked Return Value to NULL Pointer DereferenceThe product does not check for an error after calling a function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference.
• CWE-758Reliance on Undefined, Unspecified, or Implementation-Defined BehaviorThe product uses an API function, data structure, or other entity in a way that relies on properties that are not always guaranteed to hold for that entity.
