CVE-2021-3474

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.

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.

OpenEXR is a high dynamic-range (HDR) image file format originally developed by Industrial Light & Magic for use in computer imaging applications.

Security Fix(es):

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'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 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 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)

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 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 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.

Updated openexr packages fix security vulnerabilities:

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 (CVE-2021-3474, CVE-2021-3475, CVE-2021-3476, CVE-2021-3477, CVE-2021-3478, CVE-2021-3479, CVE-2021-3598, CVE-2021-3605, CVE-2021-20296, CVE-2021-23169, CVE-2021-23215, CVE-2021-26260).
