Blender before 4.5.15 and 5.x before 5.2.3 Out-of-Bounds Read via GLOB Block

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds read vulnerability in read_file_dna() that reads a GLOB block field without validating its declared length. Attackers can supply a crafted .blend file with a truncated GLOB block that, when opened, triggers the out-of-bounds read and crashes Blender.

Blender before 4.5.15 and 5.x before 5.2.3 Heap Buffer Overflow via Thumbnail Extraction

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability in the blend file thumbnail extractor caused by 32-bit integer overflow in thumb_data_vertical_flip(). Attackers can craft a .blend file with malicious TEST block dimensions that trigger an out-of-bounds write when blender-thumbnailer or the Windows shell extension previews it, causing crashes or code execution.

Blender before 4.5.15 and 5.x before 5.2.3 Heap Out-of-Bounds Access via read_struct()

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds access vulnerability in read_struct() that skips size validation when a .blend file's SDNA struct layout compares equal. Attackers can supply a crafted .blend file with short blocks so field reads, writes, and pointer dereferences overrun heap memory, causing crashes or code execution.

Blender before 4.5.15 and 5.x before 5.2.3 Heap Buffer Overflow via Point Cache

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability caused by integer overflow in ptcache_data_alloc() when reading point cache files. Attackers can supply a crafted point cache file with a large totpoint value alongside a .blend file to crash Blender or execute code as the user.

Blender before 4.5.15 and 5.x before 5.2.3 Out-of-Bounds Read via blo_bhead_id Accessors

Blender before 4.5.15 and 5.x before 5.2.3 contains an out-of-bounds read vulnerability in blo_bhead_id_* accessors in readfile.cc that read ID fields without block length checks. Attackers can supply a crafted .blend file with short ID blocks that, when browsed or appended from, causes heap over-reads leading to crashes or heap memory disclosure.

Blender 3.0.0 - 5.1.2 Out-of-Bounds Read via crafted .blend SDNA block

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.

Blender 2.34, 2.35a, 2.40, and 2.49b allows remote attackers to execute arbitrary code via a .blend file that contains Python statements in the onLoad action of a ScriptLink SDNA.

Eval injection vulnerability in the (a) kmz_ImportWithMesh.py Script for Blender 0.1.9h, as used in (b) Blender before 2.43, allows user-assisted remote attackers to execute arbitrary Python code by importing a crafted (1) KML or (2) KMZ file.

Untrusted search path vulnerability in BPY_interface in Blender 2.46 allows local users to execute arbitrary code via a Trojan horse Python file in the current working directory, related to an erroneous setting of sys.path by the PySys_SetArgv function.

Multiple unspecified vulnerabilities in Blender have unknown impact and attack vectors, related to "temporary file issues."

blender: Blender Radiance RGBE Buffer Overflow

Stack-based buffer overflow in the imb_loadhdr function in Blender 2.45 allows user-assisted remote attackers to execute arbitrary code via a .blend file that contains a crafted Radiance RGBE image.

Eval injection vulnerability in bvh_import.py in Blender 2.36 allows attackers to execute arbitrary Python code via a hierarchy element in a .bvh file, which is supplied to an eval function call.

Buffer overflow in blenderplay in Blender Player 2.37a allows attackers to execute arbitrary code via a long command line argument.

The undo save quit routine in the kernel in Blender 2.5, 2.63a, and earlier allows local users to overwrite arbitrary files via a symlink attack on the quit.blend temporary file. NOTE: this issue might be a regression of CVE-2008-1103.

Endless Infinite loop in Blender-thumnailing due to logical bugs.

blender: Null pointer reference in blender thumbnail extractor

A flaw was found in Blender 3.3.0. A null pointer dereference exists in source/blender/gpu/opengl/gl_backend.cc that may lead to loss of confidentiality and integrity.

A flaw was found in Blender 3.3.0. An interger overflow in source/blender/blendthumb/src/blendthumb_extract.cc may lead to program crash or memory corruption.

A missing bounds check in the image loader used in Blender 3.x and 2.93.8 leads to out-of-bounds heap access, allowing an attacker to cause denial of service, memory corruption or potentially code execution.

An integer overflow in the processing of loaded 2D images leads to a write-what-where vulnerability and an out-of-bounds read vulnerability, allowing an attacker to leak sensitive information or achieve code execution in the context of the Blender process when a specially crafted image file is loaded. This flaw affects Blender versions prior to 2.83.19, 2.93.8 and 3.1.

An integer underflow in the DDS loader of Blender leads to an out-of-bounds read, possibly allowing an attacker to read sensitive data using a crafted DDS image file. This flaw affects Blender versions prior to 2.83.19, 2.93.8 and 3.1.
