CVE-2018-14621
An infinite loop vulnerability was found in libtirpc before version 1.0.2-rc2.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An infinite loop vulnerability was found in libtirpc before version 1.0.2-rc2. With the port to using poll rather than select, exhaustion of file descriptors would cause the server to enter an infinite loop, consuming a large amount of CPU time and denying service to other clients until restarted.
