The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2701 advisory.
A heap-based buffer overflow vulnerability exists in Academy Software Foundation OpenEXR 2.3.0 in chunkOffsetReconstruction in ImfMultiPartInputFile.cpp that can cause a denial of service via a crafted EXR file. (CVE-2020-16587)
A flaw was found in OpenEXR in versions before 3.0.0-beta. A crafted input file supplied by an attacker, that is processed by the Dwa decompression functionality of OpenEXR’s IlmImf library, could cause a NULL pointer dereference. The highest threat from this vulnerability is to system availability.
(CVE-2021-20296)
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
(CVE-2021-23215)
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR. This is a different flaw from CVE-2021-23215. (CVE-2021-26260)
There’s a flaw in OpenEXR in versions before 3.0.0-beta. A crafted input file that is processed by OpenEXR could cause a shift overflow in the FastHufDecoder, potentially leading to problems with application availability. (CVE-2021-3474)
There is a flaw in OpenEXR in versions before 3.0.0-beta. An attacker who can submit a crafted file to be processed by OpenEXR could cause an integer overflow, potentially leading to problems with application availability. (CVE-2021-3475)
A flaw was found in OpenEXR’s B44 uncompression functionality in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to OpenEXR could trigger shift overflows, potentially affecting application availability. (CVE-2021-3476)
There’s a flaw in OpenEXR’s deep tile sample size calculations in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, subsequently leading to an out-of-bounds read. The greatest risk of this flaw is to application availability. (CVE-2021-3477)
There’s a flaw in OpenEXR’s scanline input file functionality in versions before 3.0.0-beta. An attacker able to submit a crafted file to be processed by OpenEXR could consume excessive system memory. The greatest impact of this flaw is to system availability. (CVE-2021-3478)
There’s a flaw in OpenEXR’s Scanline API functionality in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger excessive consumption of memory, resulting in an impact to system availability. (CVE-2021-3479)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
