Description

Use after free in string-interner

Affected versions of this crate did not clone contained strings when an interner is cloned. Interners have raw pointers to the contained strings, and they keep pointing the strings which the old interner owns, after the interner is cloned. If a new cloned interner is alive and the old original interner is dead, the new interner has dangling pointers to the old interner's storage, which is already dropped.

This allows an attacker to read the already freed memory. The dangling pointers are used by the interners to check a string is already interned. An attacker can do brute force attack to get the data pointed by the dangling pointer.

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 none, availability none.

Weakness class

CVE-2019-16882 is classified as CWE-416: Use After Free. Memory is used after being released, so its contents may already belong to something else.
