Package : samba CVE ID : CVE-2017-14746 CVE-2017-15275

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:


Yihan Lian and Zhibin Hu of Qihoo 360 GearTeam discovered a
use-after-free vulnerability allowing a client to compromise a SMB
server via malicious SMB1 requests.


Volker Lendecke of SerNet and the Samba team discovered that Samba
is prone to a heap memory information leak, where server allocated
heap memory may be returned to the client without being cleared.

For the oldstable distribution (jessie), these problems have been fixed in version 2:4.2.14+dfsg-0+deb8u9.

For the stable distribution (stretch), these problems have been fixed in version 2:4.5.12+dfsg-2+deb9u1.

We recommend that you upgrade your samba packages.
