CVE-2021-31439 3 Debian, Netatalk, Synology 3 Debian Linux, Netatalk, Diskstation Manager 2023-11-22 5.8 MEDIUM 8.8 HIGH
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Synology DiskStation Manager. Authentication is not required to exploit this vulnerablity. The specific flaw exists within the processing of DSI structures in Netatalk. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12326.

CVE-2019-9517 11 Apache, Apple, Canonical and 8 more 23 Traffic Server, Mac Os X, Swiftnio and 20 more 2021-06-06 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
CVE-2019-9518 10 Apache, Apple, Canonical and 7 more 19 Traffic Server, Mac Os X, Swiftnio and 16 more 2021-05-27 7.8 HIGH 7.5 HIGH

The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
CVE-2021-27648 1 Synology 1 Antivirus Essential 2021-05-12 6.5 MEDIUM 8.8 HIGH
Externally controlled reference to a resource in another sphere in quarantine functionality in Synology Antivirus Essential before 1.4.8-2801 allows remote authenticated users to obtain privilege via unspecified vectors.

CVE-2019-9514 12 Apache, Apple, Canonical and 9 more 29 Traffic Server, Mac Os X, Swiftnio and 26 more 2020-12-09 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2020-27651 1 Synology 1 Router Manager 2020-11-06 6.8 MEDIUM 8.1 HIGH
Synology Router Manager (SRM) before 1.2.4-8081 does not set the Secure flag for the session cookie in an HTTPS session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an HTTP session.
CVE-2019-9515 11 Apache, Apple, Canonical and 8 more 23 Traffic Server, Mac Os X, Swiftnio and 20 more 2020-10-22 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9499 6 Debian, Fedoraproject, Freebsd and 3 more 9 Debian Linux, Fedora, Freebsd and 6 more 2020-10-22 6.8 MEDIUM 8.1 HIGH
The implementations of EAP-PWD in wpa_supplicant EAP Peer, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit.

The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
CVE-2018-7185 6 Canonical, Hpe, Netapp and 3 more 23 Ubuntu Linux, Hpux-ntp, Hci and 20 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association.
CVE-2018-7184 5 Canonical, Netapp, Ntp and 2 more 10 Ubuntu Linux, Cloud Backup, Steelstore Cloud Integrated Storage and 7 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704.
CVE-2017-15889 1 Synology 1 Diskstation Manager 2020-05-22 6.5 MEDIUM 8.8 HIGH
