Summary

contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation.

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.

    descriptionThis update for openldap2 fixes the following issues : Security issue fixed : - CVE-2019-13565: Fixed an authentication bypass when using SASL authentication and session encryption (bsc#1143194). - CVE-2019-13057: Fixed an issue with delegated database admin privileges (bsc#1143273). - CVE-2017-17740: When both the nops module and the member of overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. (bsc#1073313) Non-security issues fixed : - Fixed broken shebang line in openldap_update_modules_path.sh (bsc#1114845). - Create files in /var/lib/ldap/ during initial start to allow for transactional updates (bsc#1111388) - Fixed incorrect post script call causing tmpfiles creation not to be run (bsc#1111388). This update was imported from the SUSE:SLE-15:Update update project.

    descriptionAccording to the versions of the openldap packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - An off-by-one error leading to a crash was discovered in openldap 2.4 when processing DNS SRV messages. If slapd was configured to use the dnssrv backend, an attacker could crash the service with crafted DNS responses.(CVE-2014-8182) - contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation.(CVE-2017-17740) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
