According to the versions of the httpd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user’s browser. A remote attacker could use this flaw to decrypt and modify session data using a padding oracle attack. (CVE-2016-0736)
It was discovered that the mod_auth_digest module of httpd did not properly check for memory allocation failures. A remote attacker could use this flaw to cause httpd child processes to repeatedly crash if the server used HTTP digest authentication. (CVE-2016-2161)
It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in conjunction with a proxy or backend server that interpreted those characters differently, a remote attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache poisoning.
(CVE-2016-8743)
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.
