Summary

Red Hat Security Advisory: piranha security and bug fix update

Severity

Important

Notes

Topic: An updated piranha package that fixes one security issue and one bug is now available for Red Hat Enterprise Linux 6. 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: Piranha provides high-availability and load-balancing services for Red Hat Enterprise Linux. The piranha packages contain various tools to administer and configure the Linux Virtual Server (LVS), as well as the heartbeat and failover components. LVS is a dynamically-adjusted kernel routing mechanism that provides load balancing, primarily for Web and FTP servers. It was discovered that the Piranha Configuration Tool did not properly restrict access to its web pages. A remote attacker able to connect to the Piranha Configuration Tool web server port could use this flaw to read or modify the LVS configuration without providing valid administrative credentials. (CVE-2013-6492) This update also fixes the following bug: * When the lvsd service attempted to start, the sem_timedwait() function received the interrupted function call (EINTR) error and exited, causing the lvsd service to fail to start. With this update, EINTR errors are correctly ignored during the start-up of the lvsd service. (BZ#1055709) All piranha users are advised to upgrade to this updated package, which contains backported patches to correct these issues.

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.
