No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
