Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-476: NULL Pointer Dereference, where the product dereferences a pointer that it expects to be valid but is null. In Magick.NET Q16 AnyCPU, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In `ReadSFWImage()` (`coders/sfw.c`), when temporary file creation fails, `read_info` is destroyed before its `filename` member is accessed, causing a NULL pointer dereference and crash. ``` AddressSanitizer:DEADLYSIGNAL ================================================================= ==1414421==ERROR: AddressSanitizer: UNKNOWN SIGNAL on unknown address 0x000000000000 (pc 0x56260222912f bp 0x7ffec0a193b0 sp 0x7ffec0a19360 T0) #0 0x56260222912f (/data/ylwang/LargeScan/targets/ImageMagick/utilities/magick+0x235f12f) ```
