RHSA-2026:15862
Vulnerability from csaf_redhat - Published: 2026-05-09 15:24 - Updated: 2026-06-18 14:43A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response, even if only a partial read was requested, or when draining the connection after a partial decompression. This can lead to a Denial of Service (DoS) condition.
A flaw was found in OpenTelemetry-Go. Repeated successful calls to the `ParseFile` function, specifically within `go.opentelemetry.io/otel/schema/v1.0` and `go.opentelemetry.io/otel/schema/v1.1`, can lead to a file descriptor leak. If a consuming application exposes repeated schema parsing to an attacker-controlled path, a remote attacker could exploit this to exhaust the process file descriptor limit, resulting in a Denial of Service (DoS) condition.
