Debian DSA-5176-1 : blender - security update

high Nessus Plugin ID 162724

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5176 advisory.

- 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. (CVE-2022-0544)

- 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. (CVE-2022-0545)

- 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.
(CVE-2022-0546)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the blender packages.

For the stable distribution (bullseye), these problems have been fixed in version 2.83.5+dfsg-5+deb11u1.
