Multiple security issues were found in the OpenEXR image library, which could result in denial of service and potentially the execution of arbitrary code when processing malformed EXR image files.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4418-1 advisory.

    It was discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were     tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or     possibly execute arbitrary code.

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

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

According to the versions of the OpenEXR package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read in     ImfOptimizedPixelReading.h. (CVE-2020-11758)

  - An issue was discovered in OpenEXR before 2.4.1. Because of integer overflows in     CompositeDeepScanLine::Data::handleDeepFrameBuffer and readSampleCountForLineBlock, an attacker can write     to an out-of-bounds pointer. (CVE-2020-11759)

  - An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during RLE uncompression     in rleUncompress in ImfRle.cpp. (CVE-2020-11760)

  - An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during Huffman     uncompression, as demonstrated by FastHufDecoder::refill in ImfFastHuf.cpp. (CVE-2020-11761)

  - An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read and write in     DwaCompressor::uncompress in ImfDwaCompressor.cpp when handling the UNKNOWN compression case.
    (CVE-2020-11762)

  - An issue was discovered in OpenEXR before 2.4.1. There is an std::vector out-of-bounds read and write, as     demonstrated by ImfTileOffsets.cpp. (CVE-2020-11763)

  - An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds write in copyIntoFrameBuffer in     ImfMisc.cpp. (CVE-2020-11764)

  - An issue was discovered in OpenEXR before 2.4.1. There is an off-by-one error in use of the ImfXdr.h read     function by DwaCompressor::Classifier::Classifier, leading to an out-of-bounds read. (CVE-2020-11765)

  - An issue was discovered in OpenEXR before 2.5.2. Invalid input could cause a use-after-free in     DeepScanLineInputFile::DeepScanLineInputFile() in IlmImf/ImfDeepScanLineInputFile.cpp. (CVE-2020-15305)

  - An issue was discovered in OpenEXR before v2.5.2. Invalid chunkCount attributes could cause a heap buffer     overflow in getChunkOffsetTableSize() in IlmImf/ImfMisc.cpp. (CVE-2020-15306)

  - 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)

  - There's a flaw in OpenEXR's ImfDeepScanLineInputFile functionality in versions prior to 3.0.5. An attacker     who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds     read. The greatest risk from this flaw is to application availability. (CVE-2021-3598)

  - There's a flaw in OpenEXR's rleUncompress functionality in versions prior to 3.0.5. An attacker who is     able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The     greatest risk from this flaw is to application availability. (CVE-2021-3605)

  - 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)
