Title
iccDEV has Undefined Behavior and Null Pointer Deference in CIccTagXmlSegmentedCurve::ToXml()
Summary
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.
Severity
7.1 (High)

Title
BlueKitchen BTstack < 1.8.1 AVRCP Browsing Target GET_FOLDER_ITEMS Handler OOB Read / Undefined Behavior
Summary
BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GET_FOLDER_ITEMS handler that fails to validate packet boundaries and attribute count data. An attacker with a paired Bluetooth Classic connection can exploit insufficient bounds checking on the attr_id parameter to cause crashes and corrupt attribute bitmap state.

Title
iccDEV: UB in CIccCalculatorFunc::ApplySequence()
Summary
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 can trigger Undefined Behavior (UB) in CIccCalculatorFunc::ApplySequence() due to invalid enum values being loaded for icChannelFuncSignature. The issue is observable under UBSan as a “load of value … not a valid value for type icChannelFuncSignature”, indicating a type/enum value confusion scenario during ICC profile processing. This issue has been patched in version 2.3.1.6.

Title
iccDEV: UB at IccUtil.cpp
Summary
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is an Undefined Behavior (UB) condition in IccUtil.cpp triggered by a crafted input profile. Under UndefinedBehaviorSanitizer, the issue is reported as invalid left shift operations on icUInt32Number (unsigned 32-bit) where the shifted value “cannot be represented” in that type. This issue has been patched in version 2.3.1.6.
Severity

Title
BACnet Stack: Undefined-behavior signed left shift in `decode_signed32()`
Summary
BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, decode_signed32() in src/bacnet/bacint.c reconstructs a 32-bit signed integer from four APDU bytes using signed left shifts. When any of the four bytes has bit 7 set (value ≥ 0x80), the left-shift operation overflows a signed int32_t, which is undefined behavior per the C standard. This is flagged thousands of times per minute by UndefinedBehaviorSanitizer on any BACnet input containing signed-integer property values with high-bit-set bytes. This vulnerability is fixed in 1.4.3.

3.7 (Low)
