Description

According to the version of the libXcursor packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • libXcursor before 1.1.15 has various integer overflows that could lead to heap buffer overflows when processing malicious cursors, e.g., with programs like GIMP.(CVE-2017-16612)

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.
