VulniPulse record published
Summary
Blender 3.0.0 through 5.1.2 contains an out-of-bounds read vulnerability that allows attackers to trigger a crash or read adjacent heap memory by supplying a crafted.blend file with a malicious signed short member_index value in the SDNA block.
The member_index field is used as an array index into the sdna->members[] array in sdna_expand_names() without bounds validation, allowing any value outside the allocated range to produce an invalid pointer subsequently passed to strlen(), resulting in a SIGSEGV crash or unintended heap memory disclosure. A flaw was found in Blender.
A remote attacker could exploit an out-of-bounds read vulnerability by providing a specially crafted.blend file. This vulnerability occurs when the application processes a malicious member_index value without proper validation, leading to an attempt to access memory outside of its allocated boundaries.
Successful exploitation can result in a denial of service, causing the application to crash, or potentially lead to the disclosure of sensitive information from the system's memory. Red Hat severity: Moderate — CVSS 6.1 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H).
Weakness: CWE-125.
