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:

CVE-2017-14746

    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.

CVE-2017-15275

    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.
