** Description changed:
- It was discovered that Linux incorrectly accounted the number of in-
- flight fds over a unix domain socket to the original opener of the file-
- descriptor. This allows another process to arbitrary deplete the
- original file-openers resource limit for the maximum of open files.
- Instead the sending processes and its struct cred should be credited.
+ The Linux kernel before 4.5 allows local users to bypass file-descriptor
+ limits and cause a denial of service (memory consumption) by leveraging
+ incorrect tracking of descriptor ownership and sending each descriptor
+ over a UNIX socket before closing it. NOTE: this vulnerability exists
+ because of an incorrect fix for CVE-2013-4312.
