CVE-2021-3156 8 Beyondtrust, Debian, Fedoraproject and 5 more 31 Privilege Management For Mac, Privilege Management For Unix\/linux, Debian Linux and 28 more 2025-04-03 7.2 HIGH 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-2019-14907 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2025-01-14 2.6 LOW 6.5 MEDIUM
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).
CVE-2017-5753 13 Arm, Canonical, Debian and 10 more 387 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 384 more 2025-01-14 4.7 MEDIUM 5.6 MEDIUM
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
CVE-2018-7170 4 Hpe, Netapp, Ntp and 1 more 10 Hpux-ntp, Hci, Solidfire and 7 more 2025-01-14 3.5 LOW 5.3 MEDIUM
ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549.
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 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-2021-26561 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 6.8 MEDIUM 8.1 HIGH
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-2021-26567 2 Faad2 Project, Synology 8 Faad2, Diskstation Manager, Diskstation Manager Unified Controller and 5 more 2025-01-14 6.5 MEDIUM 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-2021-26565 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2019-3870 3 Fedoraproject, Samba, Synology 9 Fedora, Samba, Directory Server and 6 more 2025-01-14 3.6 LOW 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-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2025-01-14 7.8 HIGH 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-2021-26560 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 5.8 MEDIUM 7.4 HIGH
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-2019-9513 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2025-01-14 7.8 HIGH 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-2018-7185 6 Canonical, Hpe, Netapp and 3 more 23 Ubuntu Linux, Hpux-ntp, Hci and 20 more 2025-01-14 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-2020-27652 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 5.1 MEDIUM 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-2020-27650 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 4.3 MEDIUM 3.7 LOW
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-2021-26564 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 5.8 MEDIUM 8.7 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-2021-26562 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 6.8 MEDIUM 8.1 HIGH
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-2020-27648 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 6.8 MEDIUM 9.0 CRITICAL
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-2021-26563 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 4.6 MEDIUM 6.7 MEDIUM
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-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2025-01-14 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.
