Blender imb_loadhdr() buffer overflow
| blender-imbloadhdr-bo (41917) |  High Risk |
Description:
Blender is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by imb_loadhdr() function. By persuading a victim to open a specially-crafted Blender (.blend) file, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
Platforms Affected:
- Blender, Blender 2.45
- Canonical, Ubuntu 6.06 LTS
- Debian, Debian Linux 4.0
- Gentoo, Linux
- MandrakeSoft, Mandrake Linux 2008.0
- MandrakeSoft, Mandrake Linux 2008.0 X86_64
- MandrakeSoft, Mandrake Linux 2008.1
- MandrakeSoft, Mandrake Linux 2008.1 X86_64
