Vulnerabilities > CVE-2018-10858 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Attack vector
NETWORK Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

This occurred because Gluster volumes are remote file systems, and shadow_copy2 only detected share paths in the local file system. This update forces the value of shadow:mountpath to '/', skipping the code related to mount point detection, and preventing this problem. However, this fix requires that the glusterfs vfs object is listed after the shadow_copy2 vfs object in the smb.conf file.

Missing input sanitization checks on some of the input parameters to LDB database layer cause the LDAP server and DNS server to crash when following a NULL pointer. Samba releases 3.2.0 to 4.8.3 (inclusive) contain an error in libsmbclient that could allow a malicious server to overwrite client heap memory by returning an extra long filename in a directory listing. Missing database output checks on the returned directory attributes from the LDB database layer cause the DsCrackNames call in the DRSUAPI server to crash when following a NULL pointer. All versions of the Samba Active Directory LDAP server from 4.0.0 onwards are vulnerable to the disclosure of confidential attribute values, both of attributes where the schema SEARCH_FLAG_CONFIDENTIAL (0x80) searchFlags bit and where an explicit Access Control Entry has been specified on the ntSecurityDescriptor. last seen 2020-06-01 modified 2020-06-02 plugin id 111722 published 2018-08-15 reporter This script is Copyright (C) 2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/111722 title FreeBSD : samba -- multiple vulnerabilities (c4e9a427-9fc2-11e8-802a-000c29a1e3ec) NASL family SuSE Local Security Checks NASL id SUSE_SU-2018-2329-1.NASL description This update for samba fixes the following issues: The following security issues were fixed : - CVE-2018-10858: Insufficient input validation on client directory listing in libsmbclient (bsc#1103411).
