-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4462-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso June 13, 2019 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : dbus CVE ID : CVE-2019-12749 Debian Bug : 930375 Joe Vennix discovered an authentication bypass vulnerability in dbus, an asynchronous inter-process communication system. The implementation of the DBUS_COOKIE_SHA1 authentication mechanism was susceptible to a symbolic link attack. A local attacker could take advantage of this flaw to bypass authentication and connect to a DBusServer with elevated privileges. The standard system and session dbus-daemons in their default configuration are not affected by this vulnerability. The vulnerability was addressed by upgrading dbus to a new upstream version 1.10.28 which includes additional fixes. For the stable distribution (stretch), this problem has been fixed in version 1.10.28-0+deb9u1. We recommend that you upgrade your dbus packages. For the detailed security status of dbus please refer to its security tracker page at: https://security-tracker.debian.org/tracker/dbus Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@xxxxxxxxxxxxxxxx -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAl0Crf5fFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0QQuA//SREVvaxhfUhUiAI8h/WVf68kOoU0HP1eC7O27D8HJRkMpiHL8bGyZmZ/ J6b2JUrLSYI7L9LZbmz3u9Nw637BRxZXMH1++lg8AuvNahc4kq5NjU+T8iMKeNNr bTuyF4GfiniwfWMI1ekaI3o7DUQLDLGpyAn2x+0jJxqH3EUPMky9YTKy3u/duE7B ZjR05Pu6W/32AELUlPBzhKABtZh+CUICJZ6aBL/9oF7ra3TcTBwTFXADqF7Jjg1W 4fZ6A0UYFBO7WRdlmuVLX9ugiy60T3DZRFmpmlRYBelExyKXK7/DcCBvpXsdsE8G 3gXmIUDR1UkG6J7zM8CGSn4ewYtuoY3L0qTM/v+EnibAdjhrDCwoWNVZb7kd3aXe OIg+iMvAlAx4ZlaplCZ+fvwzduD6iiok07tZvO6Gltw9mMZdJZtfkMdtz9EvyPQQ y8cLHArxziK2ZBscZKNuhsLF2WCxGgqGMzjA/7N4pRkWGO3ptCCc1zlzyt9xpW8r uS4Sly0b3t6OzsMhWGMxkAcxlgpizsTn2fBBjNMJTdnqLVQ/C8PreNdpGPA5FSfE 1ITpoI3av51474jcMkER/ggDfzF/T7Nr3+FhtDz3CYcRCc2Gj2UxR2OC7rLVgnFI 7RUubl1cvSie+IkI0L0aaBacB7QvpLmo0PcgaS7ZozyXgowNQSY= =2JS9 -----END PGP SIGNATURE-----
