Notes

Title of the patch: Security update for shadow

Description of the patch: This update for shadow fixes several issues. This security issue was fixed: - CVE-2017-12424: The newusers tool could have been forced to manipulate internal data structures in ways unintended by the authors. Malformed input may have lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors (bsc#1052261). These non-security issues were fixed: - bsc#1023895: Fixed man page to not contain invalid options and also prevent warnings when using these options in certain settings - bsc#980486: Reset user in /var/log/tallylog because of the usage of pam_tally2

CVE-2017-12424 (GCVE-0-2017-12424)

Vulnerability from cvelistv5 – Published: 2017-08-04 09:00 – Updated: 2024-08-05 18:36

Summary

In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
