          "text": "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.\n\nA 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-\u003ecached_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`:\n1. Unconditional flag overwrite (line 4036): `InstallFiles()` writes caller-supplied flags to `transaction-\u003ecached_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.\n2. Silent state-transition rejection (lines 873-882): `pk_transaction_set_state()` silently discards backward state transitions (e.g. `RUNNING` -\u003e `WAITING_FOR_AUTH`) but the flag overwrite at step 1 already happened. The transaction continues running with corrupted flags.\n3. Late flag read at execution time (lines 2273-2277): The scheduler\u0027s 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\u0027s flags.",
