openSUSE 15 Security Update : openexr (openSUSE-SU-2021:3844-1)

medium Nessus Plugin ID 155774

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:3844-1 advisory.

 - 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)

 - 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)

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

Solution

Update the affected packages.
