CVE-2021-3156 9 Beyondtrust, Debian, Fedoraproject and 6 more 38 Privilege Management For Mac, Privilege Management For Unix\/linux, Debian Linux and 35 more 2025-10-21 7.8 High
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character.
CVE-2018-13281 1 Synology 3 Diskstation Manager, Skynas, Vs960hd 2025-01-14 N/A
Information exposure vulnerability in SYNO.Core.ACL in Synology DiskStation Manager (DSM) before 6.2-23739-2 allows remote authenticated users to determine the existence and obtain the metadata of arbitrary files via the file_path parameter.
CVE-2019-19344 4 Canonical, Opensuse, Samba and 1 more 7 Ubuntu Linux, Leap, Samba and 4 more 2025-01-14 6.5 Medium
There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.
CVE-2019-9511 12 Apache, Apple, Canonical and 9 more 29 Traffic Server, Mac Os X, Swiftnio and 26 more 2025-01-14 7.5 High
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9513 12 Apache, Apple, Canonical and 9 more 25 Traffic Server, Mac Os X, Swiftnio and 22 more 2025-01-14 7.5 High
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.
CVE-2019-9516 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2025-01-14 6.5 Medium
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
CVE-2019-9517 12 Apache, Apple, Canonical and 9 more 28 Http Server, Traffic Server, Mac Os X and 25 more 2025-01-14 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-2020-27648 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 8.3 High
Improper certificate validation vulnerability in OpenVPN client in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2021-26561 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 9 Critical
Stack-based buffer overflow vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary code via syno_finder_site HTTP header.
CVE-2021-26566 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 8.3 High
Insertion of sensitive information into sent data vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary commands via inbound QuickConnect traffic.
CVE-2021-26567 2 Faad2 Project, Synology 8 Faad2, Diskstation Manager, Diskstation Manager Unified Controller and 5 more 2025-01-14 7.8 High
Stack-based buffer overflow vulnerability in frontend/main.c in faad2 before 2.2.7.1 allow local attackers to execute arbitrary code via filename and pathname options.
CVE-2021-26562 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 9 Critical
Out-of-bounds write vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary code via syno_finder_site HTTP header.
CVE-2021-26563 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 8.2 High
Incorrect authorization vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.4-25553 allows local users to execute arbitrary code via unspecified vectors.
CVE-2021-26564 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 8.3 High
Cleartext transmission of sensitive information vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to spoof servers via an HTTP session.
CVE-2019-3870 3 Fedoraproject, Samba, Synology 9 Fedora, Samba, Directory Server and 6 more 2025-01-14 6.1 Medium
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update.
CVE-2020-27650 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 5.8 Medium
Synology DiskStation Manager (DSM) before 6.2.3-25426-2 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-2018-7184 5 Canonical, Netapp, Ntp and 2 more 10 Ubuntu Linux, Cloud Backup, Steelstore Cloud Integrated Storage and 7 more 2025-01-14 N/A
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-2020-27652 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 8.3 High
Algorithm downgrade vulnerability in QuickConnect in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via unspecified vectors.
CVE-2021-26560 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 9 Critical
Cleartext transmission of sensitive information vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to spoof servers via an HTTP session.
CVE-2021-26565 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 8.3 High
Cleartext transmission of sensitive information vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to obtain sensitive information via an HTTP session.
