A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service.

An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. The crafted packet needs to have the correct message authentication code and a valid timestamp. When processed by the NTP daemon, it leads to an immediate crash.

Clustered Data ONTAP versions 9.11.1 through 9.11.1P2 with SnapLock configured FlexGroups are susceptible to a vulnerability which could allow an authenticated remote attacker to arbitrarily modify or delete WORM data prior to the end of the retention period.

Insufficient control flow management in some Intel(R) Processors may allow an authenticated user to potentially enable a denial of service via local access.

NTP is vulnerable to a denial of service, caused by an issue when relying on unauthenticated IPv4 time sources in ntpd. By predicting transmit timestamps for use in spoofed packets, a remote attacker could exploit this vulnerability to cause the daemon to crash or system time change.

A vulnerability was found in NTP. A security issue which enables an off-path attacker to prevent ntpd from synchronizing with NTP servers not using authentication. A server mode packet with spoofed source address sent to the client ntpd causes the next transmission to be rescheduled, even if the packet doesn't have a valid origin timestamp. If the packet is sent to the client frequently enough, it will stop polling the server and not be able to synchronize with it.

The SplObjectStorage unserialize implementation in ext/spl/splobserver.c in PHP before 7.0.12 does not verify that a key is an object, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access) via crafted serialized data.

Clustered Data ONTAP versions 8.0, 8.3.1, and 8.3.2 contain a default privileged account which under certain conditions can be used for unauthorized information disclosure.

Clustered Data ONTAP versions prior to 9.1P15 and 9.3 prior to 9.3P7 are susceptible to a vulnerability which discloses sensitive information to an unauthenticated user.

Certain versions between 2.x to 5.x (refer to advisory) of the NetApp Service Processor firmware were shipped with a default account enabled that could allow unauthorized arbitrary command execution. Any platform listed in the advisory Impact section may be affected and should be upgraded to a fixed version of Service Processor firmware IMMEDIATELY.

Fixed bug (Seg fault when loading hostile phar). (CVE-2017-11147)

lib/kadm5/kadmrpcxdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because xdrkadm5principalentrec does not validate the relationship between nkeydata and the keydata array count.

ONTAP 9 versions prior to 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, 9.12.1P2 and 9.13.1 are susceptible to a vulnerability which could allow a remote unauthenticated attacker to cause a crash of the HTTP service.

Clustered Data ONTAP versions 9.0 through 9.4 are susceptible to a vulnerability which allows remote authenticated attackers to cause a Denial of Service (DoS) in NFS and SMB environments. Exploitation of this vulnerability will allow a remote authenticated attacker to cause a Denial of Service (DoS) on affected versions of clustered Data ONTAP configured for multiprotocol access.

Clustered Data ONTAP versions prior to 9.1P16, 9.3P10 and 9.4P5 are susceptible to a vulnerability which discloses sensitive information to an unauthorized user.

NetApp Clustered Data ONTAP versions 9.x prior to 9.1P10 and 9.2P2 are susceptible to a vulnerability which allows an attacker to cause a Denial of Service (DoS) in SMB environments.

Read-Only export policy rules are not correctly enforced in Clustered Data ONTAP 8.3 Release Candidate versions and therefore may allow more than "read-only" access from authenticated SMBv2 and SMBv3 clients. This behavior has been resolved in the GA release. Customers running prior release candidates (RCs) are requested to update their systems to the NetApp Data ONTAP 8.3 GA release.

Multiple unspecified vulnerabilities in IBM Data ONTAP 7.1 before 7.1.3, as used by IBM System Storage N series Filer and IBM System Storage N series Gateway, have unknown impact and attack vectors.

NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."

Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication.

Buffer overflow in the password management functionality in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted key file.

It was found that NTP's decodenetnum() would abort with an assertion failure when processing a mode 6 or mode 7 packet containing an unusually long data value where a network address was expected. This could allow an authenticated attacker to crash ntpd.

ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (infinite loop or crash) by pointing the key file at the log file.

ntpq in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted mode 6 response packets.

The following flaw was found in ntpd:

An exploitable use-after-free vulnerability exists in the password management functionality of the Network Time Protocol. A specially crafted key file could cause a buffer overflow resulting in memory corruption. An attacker could provide a malicious password file to trigger this vulnerability.
