Title
Apache Traffic Server: A simple legitimate POST request causes a crash
Summary
A bug in POST request handling causes a crash under a certain condition.
This issue affects Apache Traffic Server: from 10.0.0 through 10.1.1, from 9.0.0 through 9.2.12.
Users are recommended to upgrade to version 10.1.2 or 9.2.13, which fix the issue.
A workaround for older versions is to set proxy.config.http.request_buffer_enabled to 0 (the default value is 0).

Summary
KDE Konsole before 25.04.2 allows remote code execution in a certain scenario. It supports loading URLs from the scheme handlers such as a ssh:// or telnet:// or rlogin:// URL. This can be executed regardless of whether the ssh, telnet, or rlogin binary is available. In this mode, there is a code path where if that binary is not available, Konsole falls back to using /bin/bash for the given arguments (i.e., the URL) provided. This allows an attacker to execute arbitrary code.

Title
Critical vulnerability in `ismp-grandpa` <v15.0.1
Summary
Hyperbridge is a hyper-scalable coprocessor for verifiable, cross-chain interoperability. A critical vulnerability was discovered in the ismp-grandpa crate, that allowed a malicious prover easily convince the verifier of the finality of arbitrary headers. This could be used to steal funds or compromise other kinds of cross-chain applications. This vulnerability is fixed in 15.0.1.

Title
Success of Certain Precompile Calls not Checked in Vyper
Summary
Vyper is a Pythonic Smart Contract Language for the EVM. When the Vyper Compiler uses the precompiles EcRecover (0x1) and Identity (0x4), the success flag of the call is not checked. As a consequence an attacker can provide a specific amount of gas to make these calls fail but let the overall execution continue. Then the execution result can be incorrect. Based on EVM's rules, after the failed precompile the remaining code has only 1/64 of the pre-call-gas left (as 63/64 were forwarded and spent). Hence, only fairly simple executions can follow the failed precompile calls. Therefore, we found no significantly impacted real-world contracts. None the less an advisory has been made out of an abundance of caution. This issue is fixed in 0.4.1.

Title
Terminating targets role delegations are not respected in tough
Summary
Missing validation of terminating delegation causes the client to continue searching the defined delegation list, even after searching a terminating delegation. This could cause the client to fetch a target from an incorrect source, altering the target contents. Users should upgrade to tough version 0.20.0 or later and ensure any forked or derivative code is patched to incorporate the new fixes.

HTTP/1.1 multiple issues with envoy.reloadable_features.http1_balsa_delay_reset in envoy
Summary
Envoy is a cloud-native high-performance edge/middle/service proxy. In affected versions envoy does not properly handle http 1.1 non-101 1xx responses. This can lead to downstream failures in networked devices. This issue has been addressed in versions 1.31.5 and 1.32.3. Users are advised to upgrade. There are no known workarounds for this issue.

Title
HTTP/1: sending overload crashes when the request is reset beforehand in envoy
Summary
Envoy is a cloud-native high-performance edge/middle/service proxy. In affected versions `sendOverloadError` is going to assume the active request exists when `envoy.load_shed_points.http1_server_abort_dispatch` is configured. If `active_request` is nullptr, only onMessageBeginImpl() is called. However, the `onMessageBeginImpl` will directly return ok status if the stream is already reset leading to the nullptr reference. The downstream reset can actually happen during the H/2 upstream reset. As a result envoy may crash. This issue has been addressed in releases 1.32.3, 1.31.5, 1.30.9, and 1.29.12. Users are advised to upgrade. Users unable to upgrade may disable `http1_server_abort_dispatch` load shed point and/or use a high threshold.
