Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. 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

A use-after-free vulnerability exists in the PDB decoder that will use a stale pointer when a memory allocation fails and that could result in a crash or a single zero byte write. ``` ==4033155==ERROR: AddressSanitizer: UNKNOWN SIGNAL on unknown address 0x000000000000 (pc 0x5589c1971b24 bp 0x7ffdcc7ae2d0 sp 0x7ffdcc7adb20 T0) ``` ``` ==4034812==ERROR: AddressSanitizer: heap-use-after-free on address 0x7f099e9f7800 at pc 0x5605d909ab20 bp 0x7ffe52045b50 sp 0x7ffe52045b40 WRITE of size 1 at 0x7f099e9f7800 thread T0 ```
