Amazon Linux 2022 : openexr (ALAS2022-2022-216)

medium Nessus Plugin ID 168571

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

The version of openexr installed on the remote host is prior to 3.1.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-216 advisory.

 - An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits.
 This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths. (CVE-2021-3933)

 - In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. (CVE-2021-3941)

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

Solution

Run 'yum update openexr' to update your system.
