Debian 9 DLA-3060-1 Critical: Blender Denial Of Service Risks

Several issues have been found in blender, a very fast and versatile 3D
modeller/renderer.


CVE-2022-0546

An out-of-bounds heap access due to missing checks in the image
loader could result in denial of service, memory corruption or
potentially code execution.

CVE-2022-0545

An integer overflow while processing 2d images might result in a
write-what-where vulnerability or an out-of-bounds read vulnerability
which could leak sensitive information or achieve code execution.

CVE-2022-0544

Crafted DDS image files could create an integer underflow in the
DDS loader which leads to an out-of-bounds read and might leak
sensitive information.


For Debian 9 stretch, these problems have been fixed in version
2.79.b+dfsg0-1~deb9u2.

We recommend that you upgrade your blender packages.
