Vulnerabilities > CVE-2013-0288 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Arthurdejong Nss-Pam-Ldapd
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
nss-pam-ldapd before 0.7.18 and 0.8.x before 0.8.11 allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code by performing a name lookup on an application with a large number of open file descriptors, which triggers a stack-based buffer overflow related to incorrect use of the FD_SET macro.
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 Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2013-0590.NASL description From Red Hat Security Advisory 2013:0590 : Updated nss-pam-ldapd packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The nss-pam-ldapd packages provide the nss-pam-ldapd daemon (nslcd), which uses a directory server to lookup name service information on behalf of a lightweight nsswitch module. An array index error, leading to a stack-based buffer overflow flaw, was found in the way nss-pam-ldapd managed open file descriptors. An attacker able to make a process have a large number of open file descriptors and perform name lookups could use this flaw to cause the process to crash or, potentially, execute arbitrary code with the privileges of the user running the process. (CVE-2013-0288) Red Hat would like to thank Garth Mollett for reporting this issue. All users of nss-pam-ldapd are advised to upgrade to these updated packages, which contain a backported patch to fix this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 68771 published 2013-07-12 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/68771 title Oracle Linux 6 : nss-pam-ldapd (ELSA-2013-0590) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-2628.NASL description Garth Mollett discovered that a file descriptor overflow issue in the use of FD_SET() in nss-pam-ldapd, which provides NSS and PAM modules for using LDAP as a naming service, can lead to a stack-based buffer overflow.
