DATE CVE VULNERABILITY TITLE RISK
2020-01-24 CVE-2015-2928 Unspecified vulnerability in Torproject TOR
The Hidden Service (HS) server implementation in Tor before 0.2.4.27, 0.2.5.x before 0.2.5.12, and 0.2.6.x before 0.2.6.7 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors.

2020-01-24 CVE-2015-2689 Improper Input Validation vulnerability in Torproject TOR
Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle pending-connection resolve states during periods of high DNS load, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets.

2020-01-24 CVE-2015-2688 Improper Handling of Exceptional Conditions vulnerability in Torproject TOR
buf_pullup in Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle unexpected arrival times of buffers with invalid layouts, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets.

2017-12-05 CVE-2016-1254 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Tor before 0.2.8.12 might allow remote attackers to cause a denial of service (client crash) via a crafted hidden service descriptor.
7.5
2017-07-02 CVE-2017-0377 Information Exposure vulnerability in Torproject TOR
Tor 0.3.x before 0.3.0.9 has a guard-selection algorithm that only considers the exit relay (not the exit relay's family), which might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families.
