blender: CVE-2005-4470

Severity: High
Published: Dec 22, 2005, 12:03:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 5.79% · Oct 27, 2026

Heap-based buffer overflow in the get_bhead function in readfile.c in Blender BlenLoader 2.0 through 2.40pre allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a .blend file with a negative bhead.len value, which causes less memory to be allocated than expected, possibly due to an integer overflow.
