Tor Contains a vulnerability related to information disclosure from log files.Information may be obtained. Tor is an implementation of the second generation of onion routing, which is mainly used to access the Internet anonymously. Tor is prone to an information-disclosure vulnerability. \nAttackers can exploit this issue to obtain sensitive information that may aid in launching further attacks. \n-----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA512\n\n- -------------------------------------------------------------------------\nDebian Security Advisory DSA-3993-1 security@debian.org\nhttps://www.debian.org/security/ Moritz Muehlenhoff\nOctober 06, 2017 https://www.debian.org/security/faq\n- -------------------------------------------------------------------------\n\nPackage : tor\nCVE ID : CVE-2017-0380\n\nIt was discovered that the Tor onion service could leak sensitive\ninformation to log files if the \"SafeLogging\" option is set to \"0\". \n\nThe oldstable distribution (jessie) is not affected. \n\nFor the stable distribution (stretch), this problem has been fixed in\nversion 0.2.9.12-1. \n\nWe recommend that you upgrade your tor packages. \n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nozt2+7pKmawWD3dJotVIu8tOMOC8lYdP5H0YLy6Qt3X3+zm1x3g=\n=7kef\n-----END PGP SIGNATURE-----\n",
