Description
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper management of internal resources when handling IPv6 protocol. Due to errors in the logic, the config matching function did not take the IPv6 address zone id into account which could lead to libcurl reusing the wrong connection when one transfer uses a zone id and a subsequent transfer uses another (or no) zone id.
Mitigation
Install updates from vendor's website.
