Multiple vulnerabilities were discovered in libwebp, the implementation of the WebP image format, which could result in denial of service, memory disclosure or potentially the execution of arbitrary code if malformed images are processed.

According to the versions of the libwebp package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in libwebp in versions before 1.0.1. An out-of-bounds read was found in function     ShiftBytes. The highest threat from this vulnerability is to data confidentiality and to the service     availability. (CVE-2018-25013)

  - A flaw was found in libwebp in versions before 1.0.1. An unitialized variable is used in function     ReadSymbol. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2018-25014)

  - A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive     amount of memory. The highest threat from this vulnerability is to the service availability.
    (CVE-2020-36332)

An update of the libwebp package has been released.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4971-1 advisory.

    It was discovered that libwebp incorrectly handled certain malformed images. If a user or automated system     were tricked into opening a specially crafted image file, a remote attacker could use this issue to cause     libwebp to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
