Package : samba
CVE ID : CVE-2018-10858 CVE-2018-10919

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-2018-10858

Svyatoslav Phirsov discovered that insufficient input validation in
libsmbclient allowed a malicious Samba server to write to the
client&#x27;s heap memory.

CVE-2018-10919

Phillip Kuhrt discovered that Samba when acting as an Active Domain
controller disclosed some sensitive attributes.

For the stable distribution (stretch), these problems have been fixed in
version 2:4.5.12+dfsg-2+deb9u3.

We recommend that you upgrade your samba packages.

tracker page at:
