Description GLSAMaker/CVETool Bot gentoo-dev 2017-12-04 01:25:41 UTC
CVE-2017-8823 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8823):
  In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before
  0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, there is a
  use-after-free in onion service v2 during intro-point expiration because the
  expiring list is mismanaged in certain error cases, aka TROVE-2017-013.

CVE-2017-8822 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8822):
  In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before
  0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, relays (that have
  incompletely downloaded descriptors) can pick themselves in a circuit path,
  leading to a degradation of anonymity, aka TROVE-2017-012.

CVE-2017-8821 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8821):
  In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before
  0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, an attacker can
  cause a denial of service (application hang) via crafted PEM input that
  signifies a public key requiring a password, which triggers an attempt by
  the OpenSSL library to ask the user for the password, aka TROVE-2017-011.

CVE-2017-8820 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8820):
  In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before
  0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, remote attackers
  can cause a denial of service (NULL pointer dereference and application
  crash) against directory authorities via a malformed descriptor, aka
  TROVE-2017-010.

CVE-2017-8819 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8819):
  In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before
  0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, the replay-cache
  protection mechanism is ineffective for v2 onion services, aka
  TROVE-2017-009. An attacker can send many INTRODUCE2 cells to trigger this
  issue.
