CVE-2011-0015
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly check the amount of compression in zlib-compressed data, which allows remote attackers to cause a denial of service via a large compression factor.

Does this matter?
Lower severity and a low EPSS score (3.10%). Track it; it rarely justifies an emergency change on its own.
