According to the versions of the libwebp package installed, the EulerOS 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)
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.
