An attacker could exploit this vulnerability\nby opening several Secure Shell (SSH) sessions with the affected\nsystem. An exploit could allow the attacker to consume available\nmemory; therefore, the affected system may become\nunreachable and unable to function properly. A hard reboot is\nneeded to restore complete functionality.\n\nCisco has confirmed the vulnerability in a Security Notice and software updates are available.\n\nTo exploit this vulnerability, the attacker must authenticate to a targeted system. This access requirement limits the possibility of a successful exploit.\n\nCustomers are advised to review the bug report in the \"Vendor Announcements\" section for a current list of affected versions.\n\nCisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.", "modified": "2013-05-29T18:39:44", "published": "2013-05-29T18:39:54", "id": "CISCO-SA-20130529-CVE-2013-1246", "href": "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20130529-CVE-2013-1246", "type": "cisco", "title": "Cisco TelePresence System t-shell Denial of Service Vulnerability ", "cvss": {"score": 6.8, "vector": "AV:N/AC:L/Au:S/C:N/I:N/A:C"}}]}
