CVE-2026-27466 1 Bigbluebutton 1 Bigbluebutton 2026-04-17 7.2 High
BigBlueButton is an open-source virtual classroom. In versions 3.0.21 and below, the official documentation for "Server Customization" on Support for ClamAV as presentation file scanner contains instructions that leave a BBB server vulnerable for Denial of Service. The flawed command exposes both ports (3310 and 7357) to the internet. A remote attacker can use this to send complex or large documents to clamd and waste server resources, or shutdown the clamd process. The clamd documentation explicitly warns about exposing this port. Enabling ufw (ubuntu firewall) during install does not help, because Docker routes container traffic through the nat table, which is not managed or restricted by ufw. Rules installed by ufw in the filter table have no effect on docker traffic. In addition, the provided example also mounts /var/bigbluebutton with write permissions into the container, which should not be required. Future vulnerabilities in clamd may allow attackers to manipulate files in that folder. Users are unaffected unless they have opted in to follow the extra instructions from BigBlueButton's documentation. This issue has been fixed in version 3.0.22.
CVE-2026-41030 1 Ascensio 1 Onlyoffice Desktopeditors 2026-04-17 6.2 Medium
In ONLYOFFICE DesktopEditors before 9.3.0, the update service allows attackers to perform actions on files with SYSTEM privileges.
CVE-2026-29093 1 Wwbn 1 Avideo 2026-04-17 8.1 High
WWBN AVideo is an open source video platform. Prior to version 24.0, the official docker-compose.yml publishes the memcached service on host port 11211 (0.0.0.0:11211) with no authentication, while the Dockerfile configures PHP to store all user sessions in that memcached instance. An attacker who can reach port 11211 can read, modify, or flush session data — enabling session hijacking, admin impersonation, and mass session destruction without any application-level authentication. This issue has been patched in version 24.0.
CVE-2026-23763 2 Twistedmatrix, Vb-audio Software 3 Twistedweb, Matrix, Matrix Coconut 2026-04-16 N/A
VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver (vbmatrixvaio64*_win10.sys). The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCTL 0x222060, maps it into user space using an MDL and MmMapLockedPagesSpecifyCache. Because the allocation size is not page-aligned, the mapping exposes the entire 0x1000-byte kernel page containing the buffer plus adjacent non-paged pool allocations with read/write permissions. An unprivileged local attacker can open a device handle (using the required 0x800 attribute flag), invoke the IOCTL to obtain the mapping, and then read or modify live kernel objects and pointers present on that page. This enables bypass of KASLR, arbitrary kernel memory read/write within the exposed page, corruption of kernel objects, and escalation to SYSTEM.
CVE-2026-28789 1 Olivetin 1 Olivetin 2026-04-16 7.5 High
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.3, an unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow. Concurrent requests to /oauth/login can trigger unsynchronized access to a shared registeredStates map, causing a Go runtime panic (fatal error: concurrent map writes) and process termination. This allows remote attackers to crash the service when OAuth2 is enabled. This issue has been patched in version 3000.10.3.
CVE-2004-0174 2 Apache, Redhat 2 Http Server, Stronghold 2026-04-16 7.5 High
Apache 1.4.x before 1.3.30, and 2.0.x before 2.0.49, when using multiple listening sockets on certain platforms, allows remote attackers to cause a denial of service (blocked new connections) via a "short-lived connection on a rarely-accessed listening socket."
CVE-2004-0872 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera does not prevent cookies that are sent over an insecure channel (HTTP) from also being sent over a secure channel (HTTPS/SSL) in the same domain, which could allow remote attackers to steal cookies and conduct unauthorized activities, aka "Cross Security Boundary Cookie Injection."
CVE-2005-2456 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2026-04-16 5.5 Medium
Array index overflow in the xfrm_sk_policy_insert function in xfrm_user.c in Linux kernel 2.6 allows local users to cause a denial of service (oops or deadlock) and possibly execute arbitrary code via a p->dir value that is larger than XFRM_POLICY_OUT, which is used as an index in the sock->sk_policy array.
CVE-2005-3106 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2026-04-16 4.7 Medium
Race condition in Linux 2.6, when threads are sharing memory mapping via CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a denial of service (deadlock) by triggering a core dump while waiting for a thread that has just performed an exec.
CVE-2006-2275 3 Canonical, Lksctp, Redhat 3 Ubuntu Linux, Stream Control Transmission Protocol, Enterprise Linux 2026-04-16 7.5 High
Linux SCTP (lksctp) before 2.6.17 allows remote attackers to cause a denial of service (deadlock) via a large number of small messages to a receiver application that cannot process the messages quickly enough, which leads to "spillover of the receive buffer."
CVE-2006-2374 1 Microsoft 3 Windows 2000, Windows 2003 Server, Windows Xp 2026-04-16 5.5 Medium
The Server Message Block (SMB) driver (MRXSMB.SYS) in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows local users to cause a denial of service (hang) by calling the MrxSmbCscIoctlCloseForCopyChunk with the file handle of the shadow device, which results in a deadlock, aka the "SMB Invalid Handle Vulnerability."
CVE-2002-0055 1 Microsoft 3 Exchange Server, Windows 2000, Windows Xp 2026-04-16 N/A
SMTP service in Microsoft Windows 2000, Windows XP Professional, and Exchange 2000 allows remote attackers to cause a denial of service via a command with a malformed data transfer (BDAT) request.
CVE-2002-1915 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 5.5 Medium
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.
CVE-2002-1914 2 Dump Project, Redhat 2 Dump, Enterprise Linux 2026-04-16 5.5 Medium
dump 0.4 b10 through b29 allows local users to cause a denial of service (execution prevention) by using flock() to lock the /etc/dumpdates file.
CVE-2002-1869 1 Heysoft 2 Eventsave, Eventsave\+ 2026-04-16 3.3 Low
Heysoft EventSave 5.1 and 5.2 and Heysoft EventSave+ 5.1 and 5.2 does not check whether the log file can be written to, which allows attackers to prevent events from being recorded by opening the log file using an application such as Microsoft's Event Viewer.
CVE-2002-1850 1 Apache 1 Http Server 2026-04-16 7.5 High
mod_cgi in Apache 2.0.39 and 2.0.40 allows local users and possibly remote attackers to cause a denial of service (hang and memory consumption) by causing a CGI script to send a large amount of data to stderr, which results in a read/write deadlock between httpd and the CGI script.
CVE-2005-3847 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-04-16 5.5 Medium
The handle_stop_signal function in signal.c in Linux kernel 2.6.11 up to other versions before 2.6.13 and 2.6.12.6 allows local users to cause a denial of service (deadlock) by sending a SIGKILL to a real-time threaded process while it is performing a core dump.
CVE-2002-0051 1 Microsoft 1 Windows 2000 2026-04-16 7.8 High
Windows 2000 allows local users to prevent the application of new group policy settings by opening Group Policy files with exclusive-read access.
CVE-2001-0893 1 Acme 1 Mini Httpd 2026-04-16 N/A
Acme mini_httpd before 1.16 allows remote attackers to view sensitive files under the document root (such as .htpasswd) via a GET request with a trailing /.
CVE-2001-0892 1 Acme 1 Thttpd 2026-04-16 N/A
Acme Thttpd Secure Webserver before 2.22, with the chroot option enabled, allows remote attackers to view sensitive files under the document root (such as .htpasswd) via a GET request with a trailing /.
