Package : samba
CVE ID : CVE-2017-12150 CVE-2017-12151 CVE-2017-12163
Multiple security issues have been discoverd in Samba, a SMB/CIFS file,
print, and login server for Unix:
CVE-2017-12150
Stefan Metzmacher discovered multiple code paths where SMB signing
was not enforced.
CVE-2017-12151
Stefan Metzmacher discovered that tools using libsmbclient did not
enforce encryption when following DFS redirects, which could allow a
man-in-the-middle attacker to read or modify connections which were
meant to be encrypted.
CVE-2017-12163
Yihan Lian and Zhibin Hu discovered that insufficient range checks
in the processing of SMB1 write requests could result in disclosure
of server memory.
For the oldstable distribution (jessie), these problems have been fixed
in version 2:4.2.14+dfsg-0+deb8u8.
For the stable distribution (stretch), these problems have been fixed in version 2:4.5.8+dfsg-2+deb9u2.
