RFR: JDK-8298248: Limit sscanf outbut width in cgroup file parsers

Wed Dec 7 08:29:46 UTC 2022

Trivial.

GET_CONTAINER_INFO_CPTR should be called with limits for the output buffers. The usual 1K provided should be large enough normally. This just prevents intentionally malformed input from causing overwriters.
