UNKNOWN Availability impact
UNKNOWN Summary
The (1) sss_autofs_cmd_getautomntent and (2) sss_autofs_cmd_getautomntbyname function in responder/autofs/autofssrv_cmd.c and the (3) ssh_cmd_parse_request function in responder/ssh/sshsrv_cmd.c in System Security Services Daemon (SSSD) before 1.9.4 allow remote attackers to cause a denial of service (out-of-bounds read, crash, and restart) via a crafted SSSD packet.
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.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2013-0508.NASL description Updated sssd packages that fix two security issues, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The System Security Services Daemon (SSSD) provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable back-end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects such as FreeIPA. A race condition was found in the way SSSD copied and removed user home directories. A local attacker who is able to write into the home directory of a different user who is being removed could use this flaw to perform symbolic link attacks, possibly allowing them to modify and delete arbitrary files with the privileges of the root user. (CVE-2013-0219) Multiple out-of-bounds memory read flaws were found in the way the autofs and SSH service responders parsed certain SSSD packets. An attacker could spend a specially crafted packet that, when processed by the autofs or SSH service responders, would cause SSSD to crash. This issue only caused a temporary denial of service, as SSSD was automatically restarted by the monitor process after the crash. (CVE-2013-0220) The CVE-2013-0219 and CVE-2013-0220 issues were discovered by Florian Weimer of the Red Hat Product Security Team. These updated sssd packages also include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked to in the References, for information on the most significant of these changes. All SSSD users are advised to upgrade to these updated packages, which upgrade SSSD to upstream version 1.9 to correct these issues, fix these bugs and add these enhancements. last seen 2020-06-01 modified 2020-06-02 plugin id 64758 published 2013-02-21 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/64758 title RHEL 6 : sssd (RHSA-2013:0508) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2013:0508.

NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2013-0508.NASL description Updated sssd packages that fix two security issues, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The System Security Services Daemon (SSSD) provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable back-end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects such as FreeIPA. A race condition was found in the way SSSD copied and removed user home directories. A local attacker who is able to write into the home directory of a different user who is being removed could use this flaw to perform symbolic link attacks, possibly allowing them to modify and delete arbitrary files with the privileges of the root user. (CVE-2013-0219) Multiple out-of-bounds memory read flaws were found in the way the autofs and SSH service responders parsed certain SSSD packets. An attacker could spend a specially crafted packet that, when processed by the autofs or SSH service responders, would cause SSSD to crash. This issue only caused a temporary denial of service, as SSSD was automatically restarted by the monitor process after the crash. (CVE-2013-0220) The CVE-2013-0219 and CVE-2013-0220 issues were discovered by Florian Weimer of the Red Hat Product Security Team. These updated sssd packages also include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked to in the References, for information on the most significant of these changes. All SSSD users are advised to upgrade to these updated packages, which upgrade SSSD to upstream version 1.9 to correct these issues, fix these bugs and add these enhancements. last seen 2020-06-01 modified 2020-06-02 plugin id 65142 published 2013-03-10 reporter This script is Copyright (C) 2013-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/65142 title CentOS 6 : sssd (CESA-2013:0508) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2013:0508 and # CentOS Errata and Security Advisory 2013:0508 respectively. # include("compat.inc"); if (description) { script_id(65142); script_version("1.10"); script_cvs_date("Date: 2020/01/06"); script_cve_id("CVE-2013-0219", "CVE-2013-0220"); script_bugtraq_id(57539); script_xref(name:"RHSA", value:"2013:0508"); script_name(english:"CentOS 6 : sssd (CESA-2013:0508)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value:"The remote CentOS host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "Updated sssd packages that fix two security issues, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.
