Description

Out of bounds access in compact_arena

Affected versions of this crate did not properly implement the generativity, because the invariant lifetimes were not necessarily dropped.

This allows an attacker to mix up two arenas, using indices created from one arena with another one. This might lead to an out-of-bounds read or write access into the memory reserved for the arena.

The flaw was corrected by implementing generativity correctly in version 0.4.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
