Ongoing Rapid Reset DDoS flood attacks exposed organizations need to patch CVE-2023-44487 immediately to head off crippling outages and business disruption.

Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress refactoring that exposed a potential denial of service on Windows if a web application opened a stream for an uploaded file but failed to close the stream. The file would never be deleted from disk creating the possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.

Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and...

A client-side enforcement of server-side security [CWE-602] vulnerability in Fortinet FortiManager version 7.4.0 and before 7.2.3 and FortiAnalyzer version 7.4.0 and before 7.2.3 may allow a remote attacker with low privileges to access a privileged web console via client side code execution.

An improper authorization vulnerability in Fortinet FortiOS 7.0.0 - 7.0.11 and 7.2.0 - 7.2.4 allows an attacker belonging to the prof-admin profile to perform elevated actions.
