NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-debugger-common package and not the rust-debugger-common package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. From 5.0.0 to before 5.0.6, the max option was being applied too late. When expanding a single large numeric range like {1..10000000}, the sequence generation loop generates all 10 million intermediate elements before the max limit is applied With max=10, the output is correctly limited to 10 items, but the process still allocates ~505 MB and spends ~800ms building the full intermediate array. This vulnerability is fixed in 5.0.6.
