TL;DR

Affected versions of this package are vulnerable to integer overflow in absl::{flat,node}_hash_{set,map} during container creation or resizing via constructors, reserve(), or rehash(). These methods fail to enforce upper bounds on size arguments, potentially causing overflows when allocating the backing store and leading to out-of-bounds memory access. The fix introduces proper validation of size arguments and updates max_size() to reflect safe limits. While exploitation is considered difficult due to limited attacker control over container sizes, applications using untrusted input should upgrade to a patched version.
