According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.(CVE-2020-29509)
The encoding/xml package in Go versions 1.15 and earlier does not correctly preserve the semantics of directives during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.(CVE-2020-29510)
The encoding/xml package in Go (all versions) does not correctly preserve the semantics of element namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.(CVE-2020-29511)
Go before 1.14.12 and 1.15.x before 1.15.5 allows Argument Injection.(CVE-2020-28367)
Go before 1.14.12 and 1.15.x before 1.15.5 allows Code Injection.(CVE-2020-28366)
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.
