#vulnerability

Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect infinite timeout which allowed connections to remain open which should have been closed. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from 9.0.0-M1 through 9.0.89. Users are recommended to upgrade to version 11.0.0-M21, 10.1.25 or 9.0.90, which fixes the issue.

### Summary A Regular Expression Denial of Service (ReDoS) vulnerability exists in the `Rack::Request::Helpers` module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted `Accept-Encoding` or `Accept-Language` headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS). ### Details The fix for https://github.com/rack/rack/security/advisories/GHSA-54rr-7fvw-6x8f was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5.

Deep Sea Electronics DSE855 is vulnerable to configuration disclosure when direct object reference is made to the Backup.bin file using an HTTP GET request. This will enable an attacker to disclose sensitive information and help her in authentication bypass, privilege escalation, and full system access.

Ubuntu Security Notice 6862-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Lukas Bernhard discovered that Firefox did not properly manage memory during garbage collection. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code.

Ubuntu Security Notice 6860-1 - Reynir Bjoernsson discovered that OpenVPN incorrectly handled terminating client connections. A remote authenticated client could possibly use this issue to keep the connection active, bypassing certain security policies. This issue only affected Ubuntu 23.10, and Ubuntu 24.04 LTS. Reynir Bjoernsson discovered that OpenVPN incorrectly handled certain control channel messages with nonprintable characters. A remote attacker could possibly use this issue to cause OpenVPN to consume resources, or fill up log files with garbage, leading to a denial of service.
