CVE-2023-4016

Published: 2 August 2023

Under some circumstances, this weakness allows a user who has access to run the “ps” utility on a machine, the ability to write almost unlimited amounts of unfiltered data into the process heap.

Notes

AuthorNote
Priority reason:
Minor DoS allowing a user to consume memory in an uncommon configuration
mdeslaur
A user having access to the "ps" utility can consume memory.
Having users able to access ps and not consume memory in other
ways is a pretty unrealistic scenario.
