SUSE SLES11 Security Update : OpenEXR (SUSE-SU-2021:14846-1)

medium Nessus Plugin ID 155801

Language:

Synopsis

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

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14846-1 advisory.

 - A flaw was found in OpenEXR's B44Compressor. This flaw allows an attacker who can submit a crafted file to be processed by OpenEXR, to exhaust all memory accessible to the application. The highest threat from this vulnerability is to system availability. (CVE-2021-20298)

 - A flaw was found in OpenEXR's hufUncompress functionality in OpenEXR/IlmImf/ImfHuf.cpp. This flaw allows an attacker who can submit a crafted file that is processed by OpenEXR, to trigger an integer overflow.
 The highest threat from this vulnerability is to system availability. (CVE-2021-20300)

 - A flaw found in function dataWindowForTile() of IlmImf/ImfTiledMisc.cpp. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, leading to an out-of-bounds write on the heap. The greatest impact of this flaw is to application availability, with some potential impact to data integrity as well. (CVE-2021-20303)

 - A flaw was found in OpenEXR's hufDecode functionality. This flaw allows an attacker who can pass a crafted file to be processed by OpenEXR, to trigger an undefined right shift error. The highest threat from this vulnerability is to system availability. (CVE-2021-20304)

 - 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

Update the affected OpenEXR and / or OpenEXR-32bit packages.
