Summary

Red Hat Security Advisory: sudo security update

Severity

Important

Notes

Topic: An updated sudo package that fixes one security issue is now available for Red Hat Enterprise Linux 5. 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.

Details: The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root. A flaw was found in the way sudo handled Runas specifications containing both a user and a group list. If a local user were authorized by the sudoers file to perform their sudo commands with the privileges of a specified user and group, they could use this flaw to run those commands with the privileges of either an arbitrary user or group on the system. (CVE-2010-2956) Red Hat would like to thank Markus Wuethrich of Swiss Post - PostFinance for reporting this issue. Users of sudo should upgrade to this updated package, which contains a backported patch to correct this issue.

CVE-2010-2956

Sudo 1.7.0 through 1.7.4p3, when a Runas group is configured, does not properly handle use of the -u option in conjunction with the -g option, which allows local users to gain privileges via a command line containing a "-u root" sequence.

6.0 ()

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.
