Red Hat Security Advisory: Satellite 6.18.5 Async Update

Important

A flaw was found in Django. A remote attacker can exploit this vulnerability by sending a crafted request containing multiple duplicate headers to the ASGIRequest component. This can lead to a potential Denial of Service (DoS), making the affected system unavailable to legitimate users.

CWE-167 - Improper Handling of Additional Special Element

A flaw was found in Python-Markdown. Parsing crafted markdown content containing malformed HTML-like sequences causes html.parser.HTMLParser to raise an unhandled AssertionError. This unhandled exception allows an attacker to cause an application crash and potentially disclose sensitive information via its stack trace.

CWE-617 - Reachable Assertion

A flaw was found in Django. A remote attacker could inject SQL commands by manipulating the band index parameter during raster lookups on `RasterField` (only implemented on PostGIS). This SQL injection vulnerability could lead to unauthorized information disclosure, data alteration, or denial of service.

CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

A flaw was found in Django. A remote attacker can exploit this vulnerability by providing crafted inputs containing a large number of unmatched HTML end tags to the `django.utils.text.Truncator.chars()` and `Truncator.words()` methods (when `html=True`), or through the `truncatechars_html` and `truncatewords_html` template filters. This can lead to a denial-of-service (DoS) condition, making the application unavailable to legitimate users.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in Django. This vulnerability allows a remote attacker to perform SQL injection by using specially crafted control characters within column aliases. When these crafted aliases are passed through dictionary expansion to `QuerySet` methods like `annotate()` or `values()`, it can lead to the execution of arbitrary SQL commands. This could result in unauthorized access to sensitive data or modification of information within the database.

CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

A flaw was found in Django. A remote attacker could exploit a SQL injection vulnerability in the `.QuerySet.order_by()` method. This occurs when column aliases containing periods are used, and the same alias is also present in `FilteredRelation` via a specially crafted dictionary. Successful exploitation could lead to unauthorized information disclosure or arbitrary code execution within the database.

CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

A flaw was found in pyOpenSSL. The set_cookie_generate_callback callback function can be used to generate DTLS cookies. When the callback returns a cookie string or byte sequence longer than 256 bytes, a buffer overflow can be triggered due to a missing bounds checking before copying the data to a fixed-size buffer provided by the underlying OpenSSL library.

CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
