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.

(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)

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)
