According to the versions of the linux-sgx packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise.(CVE-2024-0727)
Tenable has extracted the preceding description block directly from the EulerOS linux-sgx security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the applicationโs self-reported version number.
