According to the versions of the sane-backends packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A heap buffer overflow in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-080. (CVE-2020-12861)
A heap buffer overflow in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-084. (CVE-2020-12865)
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.
