Summary
Red Hat Security Advisory: satellite/iop-vulnerability-engine-rhel9 container image available as a Technology Preview
Severity
Important
Notes
Topic: A new satellite/iop-vulnerability-engine-rhel9 container image is now available as a Technology Preview in the Red Hat container registry.
Details: Red Hat Lightspeed in Satellite analyzes system health and configuration by applying predefined rules to a small set of local data, such as installed packages, running services, and configuration settings. When you install Red Hat Lightspeed in Satellite locally, you can generate Red Hat Lightspeed recommendations without sending system data to Red Hat services.

A flaw was found in OpenSSL. The Datagram Transport Layer Security (DTLS) retransmission mechanism fails to properly handle handshake message writes that are suspended before completion. A remote attacker could exploit this vulnerability during handshake message retransmission, causing OpenSSL to read past the message buffer or overwrite internal state required to resume writing. This issue can result in information disclosure through out-of-bounds memory reads or cause a Denial of Service (DoS) by crashing the process.

Vendor Fix fix
Threats
Impact Important

A flaw was found in GitPython. A remote attacker could exploit a regular expression denial of service (ReDoS) vulnerability by crafting a malicious commit object. Specifically, a malformed author field containing an unterminated angle bracket can cause excessive processing, leading to the exhaustion of CPU resources and a denial of service for over two minutes per commit access.

CWE-1333 - Inefficient Regular Expression Complexity
Affected products
Fixed 1 product, the same list as for CVE-2026-84782
Threats
Impact Important

A flaw was found in rustls-webpki. A remote attacker, by influencing an application to parse a specially crafted Certificate Revocation List (CRL) that contains an empty `onlySomeReasons` value in its `issuingDistributionPoint` extension, could trigger a panic. This vulnerability leads to a denial of service (DoS) in applications that explicitly enable CRL revocation checking.

CWE-125 - Out-of-bounds Read
Affected products
Fixed 1 product, the same list as for CVE-2026-84782
Threats
Impact Important

A flaw was found in GitPython. A remote attacker can achieve arbitrary code execution by supplying specially crafted repository URLs that are processed without proper protocol validation. Because the library forwards untrusted URLs and input parameters to the underlying Git utility without adequate sanitization, an attacker can execute arbitrary system commands within the context of the host application.

CWE-88 - Improper Neutralization of Argument Delimiters in a Command

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
