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-4339-1 advisory.

    Brandon Perry 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. This issue only applied to Ubuntu 20.04 LTS. (CVE-2017-9111,     CVE-2017-9113, CVE-2017-9115)

    Tan Jie 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. This issue only applied to Ubuntu 20.04 LTS. (CVE-2018-18444)

    Samuel Gro 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. (CVE-2020-11758, CVE-2020-11759, CVE-2020-11760, CVE-2020-11761,     CVE-2020-11762, CVE-2020-11763, CVE-2020-11764)

    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.
    (CVE-2020-11765)

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.

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2020-004, 10.14.x prior to 10.14.6 Security Update 2020-004, or 10.15.x prior to 10.15.6. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious     access point, or an adjacent user, to determine if a connected user is using a VPN, make positive     inferences about the websites they are visiting, and determine the correct sequence and acknowledgement     numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that     is needed for an attacker to hijack active connections inside the VPN tunnel. (CVE-2019-14899)

  - cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote     denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an     off-by-one error in _sasl_add_string in common.c in cyrus-sasl. (CVE-2019-19906)

  - In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands     via scripting interfaces (e.g., Python, Ruby, or Lua). (CVE-2019-20807)

  - rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in the     synchronization path. (CVE-2014-9512)

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

Security Fix(es) :

  - OpenEXR: out-of-bounds read during Huffman uncompression     (CVE-2020-11761)

  - OpenEXR: std::vector out-of-bounds read and write in     ImfTileOffsets.cpp (CVE-2020-11763)

  - OpenEXR: out-of-bounds write in copyIntoFrameBuffer     function in ImfMisc.cpp (CVE-2020-11764)

The version of OpenEXR installed on the remote host is prior to 1.7.1-8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1499 advisory.

    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 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)

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202107-27 (OpenEXR: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenEXR. Please review       the CVE identifiers referenced below for details.
  Impact :

    Please review the referenced CVE identifiers for details.
  Workaround :

    There is no known workaround at this time.

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.

For Debian 9 stretch, these problems have been fixed in version 2.2.0-11+deb9u1.

We recommend that you upgrade your openexr packages.
