NVD Description

Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A use-after-free issue was discovered in Tor 0.3.2.x before 0.3.2.10. It allows remote attackers to cause a denial of service (relay crash) because the KIST implementation allows a channel to be added more than once in the pending list.
