Description

According to the versions of the graphite2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • Various vulnerabilities have been discovered in Graphite2. An attacker able to trick an unsuspecting user into opening specially crafted font files in an application using Graphite2 could exploit these flaws to disclose potentially sensitive memory, cause an application crash, or, possibly, execute arbitrary code. (CVE-2017-7771, CVE-2017-7772, CVE-2017-7773, CVE-2017-7774, CVE-2017-7775, CVE-2017-7776, CVE-2017-7777, CVE-2017-7778)

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.
