A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected `0\r\n` termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.

Red Hat Security Advisory 2024-4352-03 - An update for kernel-rt is now available for Red Hat Enterprise Linux 8. Issues addressed include double free, memory leak, null pointer, spoofing, and use-after-free vulnerabilities.

The US military has abandoned its half-century dream of a suit of powered armor in favor of a “hyper enabled operator,” a tactical AI assistant for special operations forces.

### Impact There is a vulnerability in Traefik that allows bypassing IP allow-lists via HTTP/3 early data requests in QUIC 0-RTT handshakes sent with spoofed IP addresses. ### Patches - https://github.com/traefik/traefik/releases/tag/v2.11.6 - https://github.com/traefik/traefik/releases/tag/v3.0.4 - https://github.com/traefik/traefik/releases/tag/v3.1.0-rc3 ### Workarounds No workaround. ### For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues). <details> <summary>Original Description</summary> ### Summary Bypassing IP allow-lists in traefik via HTTP/3 early data requests in QUIC 0-RTT handshakes sent with spoofed IP addresses. ### Details HTTP/3 supports sending HTTP requests as early data during QUIC 0-RTT handshakes to reduce RTT overhead for connection resumptions. Early data is sent and received before the handshake is completed and the client's IP address is validated. The initia...

### Impact The Pomerium user info page (at `/.pomerium`) unintentionally included serialized OAuth2 access and ID tokens from the logged-in user's session. These tokens are not intended to be exposed to end users. This issue may be more severe in the presence of an XSS vulnerability in an upstream application proxied through Pomerium. If an attacker could insert a malicious script onto a web page proxied through Pomerium, that script could access these tokens by making a request to the `/.pomerium` endpoint. Upstream applications that authenticate only the ID token may be vulnerable to user impersonation using a token obtained in this manner. Note that an OAuth2 access token or ID token by itself is not sufficient to hijack a user's Pomerium session. Upstream applications should not be vulnerable to user impersonation via these tokens provided: - the application verifies the [Pomerium JWT](https://www.pomerium.com/docs/capabilities/getting-users-identity) for each request, - the co...

103 models of Toshiba Multi-Function Printers (MFP) are vulnerable to 40 different vulnerabilities including remote code execution, local privilege escalation, xml injection, and more.

Ubuntu Security Notice 6877-1 - It was discovered that LibreOffice incorrectly performed TLS certificate verification when the LibreOfficeKit library is being used by third-party components. A remote attacker could possibly use this issue to obtain sensitive information.

308 different models of Sharp Multi-Function Printers (MFP) are vulnerable to 18 different vulnerabilities including remote code execution, local file inclusion, credential disclosure, and more.

Ubuntu Security Notice 6871-1 - It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.

Siemens CP-8000, CP-8021, CP8-022, CP-8031, CP-8050, and SICORE products suffer from buffer overread, privilege escalation, and unsafe storage vulnerabilities.
