The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2020:4542 advisory.

  - cryptsetup: Out-of-bounds write when validating segments (CVE-2020-14382)

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:4542 advisory.

  - cryptsetup: Out-of-bounds write when validating segments (CVE-2020-14382)

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

According to the version of the cryptsetup packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A vulnerability was found in upstream release     cryptsetup-2.2.0 where, there's a bug in LUKS2 format     validation code, that is effectively invoked on every     device/image presenting itself as LUKS2 container. The     bug is in segments validation code in file     'lib/luks2/luks2_json_metadata.c' in function     hdr_validate_segments(struct crypt_device *cd,     json_object *hdr_jobj) where the code does not check     for possible overflow on memory allocation used for     intervals array (see statement 'intervals =     malloc(first_backup * sizeof(*intervals))'). Due to the     bug, library can be *tricked* to expect such allocation     was successful but for far less memory then originally     expected. Later it may read data FROM image crafted by     an attacker and actually write such data BEYOND     allocated memory.(CVE-2020-14382)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
