Name of the Vulnerable Software and Affected Versions
Blender versions 3.0.0 through 5.1.2
Description
An out-of-bounds read occurs when processing a crafted .blend file containing a malicious signed short
member index value within the SDNA block. The member index field is used as an array index for the sdna->members[] array in the sdna expand names() function without proper bounds validation. This allows values outside the allocated range to create an invalid pointer that is passed to strlen(), leading to a SIGSEGV crash or the disclosure of adjacent heap memory.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
