Polkit's polkit-agent-helper-1 setuid binary fails to bound input length on stdin, allowing local authenticated users to trigger out-of-memory conditions and deny system availability. An attacker with local login privileges can supply excessively long input to exhaust memory resources, causing a system-wide denial of service. No public exploit code or active exploitation has been confirmed at the time of analysis.
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. Rated medium severity (CVSS 6.7).
A flaw was found in PolicyKit (aka polkit) 0.115 that allows a user with a uid greater than INT_MAX to successfully execute any systemctl command. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
A flaw was found in polkit before version 0.116. Rated medium severity (CVSS 4.4), this vulnerability is low attack complexity.
pkexec, when used with --user nonpriv, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer. Rated high severity (CVSS 7.8). No vendor patch available.
Integer overflow in the authentication_agent_new_cookie function in PolicyKit (aka polkit) before 0.113 allows local users to gain privileges by creating a large number of connections, which triggers. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity. No vendor patch available.
PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (memory corruption and polkitd daemon crash) and possibly gain privileges via unspecified vectors, related to. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity. No vendor patch available.
The polkit_backend_action_pool_init function in polkitbackend/polkitbackendactionpool.c in PolicyKit (aka polkit) before 0.113 might allow local users to gain privileges via duplicate action IDs in. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity. No vendor patch available.
The authentication_agent_new function in polkitbackend/polkitbackendinteractiveauthority.c in PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (NULL pointer. Rated low severity (CVSS 2.1), this vulnerability is low attack complexity. No vendor patch available.
Race condition in PolicyKit (aka polkit) allows local users to bypass intended PolicyKit restrictions and gain privileges by starting a setuid or pkexec process before the authorization check is. Rated high severity (CVSS 7.2), this vulnerability is low attack complexity.
