Security Vulnerabilities
ThinkPHP 5.0.23 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by invoking functions through the routing parameter. Attackers can craft requests to the index.php endpoint with malicious function parameters to execute system commands with application privileges.

Textpad 8.1.2 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long buffer string through the Run command interface. Attackers can paste a 5000-byte payload into the Command field via Tools > Run to trigger a buffer overflow that crashes the application.

Angry IP Scanner for Linux 3.5.3 contains a denial of service vulnerability that allows local attackers to crash the application by supplying malformed input to the port selection field. Attackers can craft a malicious string containing buffer overflow patterns and paste it into the Preferences Ports tab to trigger an application crash.

LanSpy 2.0.1.159 contains a local buffer overflow vulnerability in the scan section that allows local attackers to execute arbitrary code by exploiting structured exception handling mechanisms. Attackers can craft malicious payloads using egghunter techniques to locate and execute shellcode, triggering code execution through SEH chain manipulation and controlled jumps.

PackageKit is a a D-Bus abstraction layer that allows the user to manage packages in a secure way using a cross-distro, cross-architecture API. PackageKit between and including versions 1.0.2 and 1.3.4 is vulnerable to a time-of-check time-of-use (TOCTOU) race condition on transaction flags that allows unprivileged users to install packages as root and thus leads to a local privilege escalation. This is patched in version 1.3.5.
A local unprivileged user can install arbitrary RPM packages as root, including executing RPM scriptlets, without authentication. The vulnerability is a TOCTOU race condition on `transaction->cached_transaction_flags` combined with a silent state-machine guard that discards illegal backward transitions while leaving corrupted flags in place. Three bugs exist in `src/pk-transaction.c`:
1. Unconditional flag overwrite (line 4036): `InstallFiles()` writes caller-supplied flags to `transaction->cached_transaction_flags` without checking whether the transaction has already been authorized/started. A second call blindly overwrites the flags even while the transaction is RUNNING.
2. Silent state-transition rejection (lines 873–882): `pk_transaction_set_state()` silently discards backward state transitions (e.g. `RUNNING` → `WAITING_FOR_AUTH`) but the flag overwrite at step 1 already happened. The transaction continues running with corrupted flags.
3. Late flag read at execution time (lines 2273–2277): The scheduler's idle callback reads cached_transaction_flags at dispatch time, not at authorization time. If flags were overwritten between authorization and execution, the backend sees the attacker's flags.

A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend.

A rogue backend can send a crafted SVCB response to a Discovery of Designated Resolvers request, when requested via either the autoUpgrade (Lua) option to newServer or auto_upgrade (YAML) settings. DDR upgrade is not enabled by default.
