Summary

Red Hat Security Advisory: pcs security, bug fix, and enhancement update

Severity

Moderate

Notes

Topic: An update for pcs is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: The pcs packages provide a command-line configuration system for the Pacemaker and Corosync utilities. The following packages have been upgraded to a newer upstream version: pcs (0.9.152). (BZ#1299847) Security Fix(es): * A Cross-Site Request Forgery (CSRF) flaw was found in the pcsd web UI. A remote attacker could provide a specially crafted web page that, when visited by a user with a valid pcsd session, would allow the attacker to trigger requests on behalf of the user, for example removing resources or restarting/removing nodes. (CVE-2016-0720) * It was found that pcsd did not invalidate cookies on the server side when a user logged out. This could potentially allow an attacker to perform session fixation attacks on pcsd. (CVE-2016-0721) These issues were discovered by Martin Prpic (Red Hat Product Security). Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
