Samba < 4.15.12, 4.16.x < 4.16.7, and 4.17.x < 4.17.3 32-Bit Systems Buffer Overflow

high Nessus Plugin ID 168018

Language:

Synopsis

The remote Samba server is potentially affected by a buffer overflow vulnerability

Description

The version of Samba running on the remote host is prior to 4.15.12, 4.16.x prior to 4.16.7, or 4.17.x prior to 4.17.3.
It is, therefore, potentially affected by a buffer overflow condition in the bundled Kerberos libraries due to a miss calculation of bytes to allocate for a buffer. An authenticated, remote attacker can exploit this, via a specially crafted ticket containing Privilege Attribute Certificates, to cause a denial of service condition or read beyond the memory bounds.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Samba version 4.15.12, 4.16.7, 4.17.3 or later.
