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.

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

  - 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)

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

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 ALAS2-2023-2078 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)

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)

    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)

    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)

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.

    Multiple security vulnerabilities have been found in OpenEXR, command-line     tools and a library for the OpenEXR image format. Buffer overflows or     out-of-bound reads could lead to a denial of service (application crash) if     a malformed image file is processed.

    For Debian 10 buster, these problems have been fixed in version     2.2.1-4.1+deb10u2.

    We recommend that you upgrade your openexr packages.
