CVE-2012-5573
Last modified
CVE-2012-5573 is a vulnerability of currently unknown severity. The connection_edge_process_relay_cell function in or/relay.c in Tor before 0.2.3.25 maintains circuits even if an unexpected SENDME cell arrives, which might allow remote attackers to cause a denial of service (memory consumption or excessive cell reception rate) or bypass intended flow-control restrictions via a RELAY_COMMAND_SENDME command.. EPSS estimates a 3.15% chance of exploitation in the next 30 days.
