Summary

Security update for sudo

Severity

Moderate

Notes

Title of the patch: Security update for sudo

Description of the patch: This update for sudo fixes the following issues: - Fix two security vulnerabilities that allowed users to bypass sudo's NOEXEC functionality: * noexec bypass via system() and popen() [CVE-2016-7032, bsc#1007766] * noexec bypass via wordexp() [CVE-2016-7076, bsc#1007501] - The SSSD plugin would occasionally crash sudo with an 'internal error'. This issue has been fixed. [bsc#948973] - The SSSD plugin would occasionally apply @netgroups rules from LDAP to all users rather than the @netgroup. This issue is now fixed. [bsc#966755] - When the SSSD plugin was used and a local user ran sudo, an e-mail used to be sent to administrator because SSSD did not support sudo rules for local users. This message did not signify an error, however, it was only noise. [bsc#1008043]

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.
