Amazon Linux 2022 : openexr, openexr-devel, openexr-libs (ALAS2022-2022-061)

medium Nessus Plugin ID 164782

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-061 advisory.

An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t is less than 64 bits. This issue could cause an invalid bytesPerLine and maxBytesPerLine value, which leads to problems with application stability or 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update --releasever=2022.0.20220504 openexr' to update your system.
