-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3816-2 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso April 02, 2017 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : samba Debian Bug : 858564 858590 858648 859101 Two regressions were introduced by the samba update in DSA-3816-1. Updated packages are now available to address these problems. Additionally a regression from DSA-3548-1 causing `net ads join` to freeze when run a second time is fixed along with this update. For reference, the original advisory text follows. Jann Horn of Google discovered a time-of-check, time-of-use race condition in Samba, a SMB/CIFS file, print, and login server for Unix. A malicious client can take advantage of this flaw by exploiting a symlink race to access areas of the server file system not exported under a share definition. For the stable distribution (jessie), these problems have been fixed in version 2:4.2.14+dfsg-0+deb8u5. We recommend that you upgrade your samba packages.
