-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4135-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso March 13, 2018 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : samba CVE ID : CVE-2018-1050 CVE-2018-1057 Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix. The Common Vulnerabilities and Exposures project identifies the following issues: CVE-2018-1050 It was discovered that Samba is prone to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. https://www.samba.org/samba/security/CVE-2018-1050.html CVE-2018-1057 Bjoern Baumbach from Sernet discovered that on Samba 4 AD DC the LDAP server incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users passwords, including administrative users. https://www.samba.org/samba/security/CVE-2018-1057.html https://wiki.samba.org/index.php/CVE-2018-1057 For the oldstable distribution (jessie), CVE-2018-1050 will be addressed in a later update. Unfortunately the changes required to fix CVE-2018-1057 for Debian oldstable are too invasive to be backported. Users using Samba as an AD-compatible domain controller are encouraged to apply the workaround described in the Samba wiki and upgrade to Debian stretch. For the stable distribution (stretch), these problems have been fixed in version 2:4.5.12+dfsg-2+deb9u2. We recommend that you upgrade your samba packages. For the detailed security status of samba please refer to its security tracker page at: https://security-tracker.debian.org/tracker/samba 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----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAlqnnphfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0Q7xQ//bGpp8gLoxYxiaUaVJCxN08djsPRx3mas0VF319Te6Fg/iLntI2LzSx6b HmdtJ/ZZz6lLrvG5LMfeqZwgFlztUoJ8JR0Mjd+m83Rf9ccX+8dlPJQq8509WuYM tBj+DmLpLQMLxAfMDWohO3A3qDGw2jOrjsbv1Viex4NYn7JWsQVpiYb3L27pn6kp hl88nu5doRFk57bID5TjgFnA14gMJQjXj7E3y/4bc5B07ee8tantewcLYL3Nknvw r5aVZ3/Hvxs+6sArKNBwjynFuKNFPhgtE2LGOW3hp17dYX4e/uMHiyrnHjXnfI/j Ak7TZHi/vq7EWApbtvXcFCTZ3dqWlrxC2WSge0Xl5oT8hMhV3IdvoIhO6rs/wgQ4 N2ZhtphVG/8ZKhoQx5h+f5eJnuvP7iIPHmviHcgE3im9mKl/XrXhHL0rPCB2qzvH 3I5BixpwyMLU6cunGWkMHahobjPdlnl5aOpMedBnCs2DjnIRi+Jy5NJmaPdyWSeL BSkxPUrUwUhxhH3P1AChctJWwNNPJAlcoSR7EWV3M9AQhelrWdACOMb1iOK+VCTm 65UGzyGagkUW+ui/azeypHvBZM07CwS+69J5CBGVFNfHvvFGZ9HEGndMhItV7eok Ta27LiGU+Fq1S7h5QiPWmyUo5qsD9Vefh056JqMQtQVCEdwLmnw= =ajOu -----END PGP SIGNATURE-----
