- CVEs with nessus.description==According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- It was found that the tmpdir and tempfile modules did not sanitize their file name argument. An attacker with control over the name could create temporary files and directories outside of the dedicated directory.(CVE-2018-6914)
- A integer underflow was found in the way String#unpack decodes the unpacking format. An attacker, able to control the unpack format, could use this flaw to disclose arbitrary parts of the application's memory.(CVE-2018-8778)
- It was found that the UNIXSocket::open and UNIXServer::open ruby methods did not handle the NULL byte properly. An attacker, able to inject NULL bytes in the socket path, could possibly trigger an unspecified behavior of the ruby script.(CVE-2018-8779)
- It was found that the methods from the Dir class did not properly handle strings containing the NULL byte.
An attacker, able to inject NULL bytes in a path, could possibly trigger an unspecified behavior of the ruby script.(CVE-2018-8780)
- It was found that WEBrick could be forced to use an excessive amount of memory during the processing of HTTP requests, leading to a Denial of Service. An attacker could use this flaw to send huge requests to a WEBrick application, resulting in the server running out of memory.(CVE-2018-8777)
- RubyGems version Ruby 2.2 series: 2.2.9 and earlier, Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier, prior to trunk revision 62422 contains a infinite loop caused by negative size vulnerability in ruby gem package tar header that can result in a negative size could cause an infinite loop.. This vulnerability appears to have been fixed in 2.7.6.(CVE-2018-1000075)

This vulnerability appears to have been fixed in 2.7.6.(CVE-2018-1000076)
