Summary

Red Hat Security Advisory: libunwind security update

Severity

Low

Notes

Topic: Updated libunwind packages that fix a security flaw are now available for Red Hat Enterprise Linux OpenStack Platform 6.0. Red Hat Product Security has rated this update as having Low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Details: Libunwind provides a C ABI to determine the call-chain of a program. An off by one array indexing error was found in libunwind. It is unlikely that any exploitable attack vector exists in current builds or supported usage. (CVE-2015-3239) This issue was discovered by Paolo Bonzini of Red Hat. All users of libunwind are advised to upgrade to these updated packages, which correct this issue.

CVE-2015-3239

An off-by-one array indexing error was found in the libunwind API, which could cause an error when reading untrusted binaries or dwarf debug info data. Red Hat products do not call the API in this way; and it is unlikely that any exploitable attack vector exists in current builds or supported usage.

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.
