SUSE CVE-2013-7295

Tor before 0.2.4.20, when OpenSSL 1.x is used in conjunction with a certain HardwareAccel setting on Intel Sandy Bridge and Ivy Bridge platforms, does not properly generate random numbers for 1 relay identity keys and 2 hidden-service identity keys, which might make it easier for remote attackers...

SUSE CVE-2014-5117

Tor before 0.2.4.23 and 0.2.5 before 0.2.5.6-alpha maintains a circuit after an inbound RELAYEARLY cell is received by a client, which makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAYEARLY cells as a means of communicating...

SUSE CVE-2015-2688

SUSE CVE-2015-2689

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...

SUSE CVE-2015-2928

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...

SUSE CVE-2015-2929

The Hidden Service HS client 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 servers to cause a denial of service assertion failure and application exit via a malformed HS descriptor...

SUSE CVE-2015-7665

Tails before 1.7 includes the wget program but does not prevent automatic fallback from passive FTP to active FTP, which allows remote FTP servers to discover the Tor client IP address by reading a 1 PORT or 2 EPRT command. NOTE: within wget itself, the automatic fallback is not considered a...

SUSE CVE-2016-1254

Tor before 0.2.8.12 might allow remote attackers to cause a denial of service client crash via a crafted hidden service descriptor...

SUSE CVE-2016-8860

Tor before 0.2.8.9 and 0.2.9.x before 0.2.9.4-alpha had internal functions that were entitled to expect that buft data had NUL termination, but the implementation of or/buffers.c did not ensure that NUL termination was present, which allows remote attackers to cause a denial of service client,...

SUSE CVE-2016-9079

A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox 50.0.2, Firefox ESR 45.5.1, and Thunderbird 45.5.1...

SUSE CVE-2017-0375

The hidden-service feature in Tor before 0.3.0.8 allows a denial of service assertion failure and daemon exit in the relaysendendcellfromedge function via a malformed BEGIN cell...

SUSE CVE-2017-0376

The hidden-service feature in Tor before 0.3.0.8 allows a denial of service assertion failure and daemon exit in the connectionedgeprocessrelaycell function via a BEGINDIR cell on a rendezvous circuit...

SUSE CVE-2017-0377

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...

SUSE CVE-2017-0380

The rendserviceintroestablished function in or/rendservice.c in Tor before 0.2.8.15, 0.2.9.x before 0.2.9.12, 0.3.0.x before 0.3.0.11, 0.3.1.x before 0.3.1.7, and 0.3.2.x before 0.3.2.1-alpha, when SafeLogging is disabled, allows attackers to obtain sensitive information by leveraging access to t...
