Red Hat has assigned a CVE ID to this issue: CVE-2018-3135. Upgrade as soon as possible.
Background:
A flaw in the fetch_url function of Red Hat Enterprise Linux 7.5 and earlier allows authenticated attackers to cause a denial of service (system crash) via a request for a specially crafted URL.
Description
This issue was discovered when using the Linux kernel package in Red Hat Enterprise Linux 5, 6, 7.
Certain system calls that are used for asynchronous I/O control operations may not return an error code. This issue can cause the process to continue running even if an application’s I/O control request fails. As a result, a malicious user can cause use-after-free errors and possibly execute arbitrary code with root privileges by leveraging this flaw.
