CVE-2026-2738 1 Openvpn 1 Ovpn-dco-win 2026-04-17 N/A
Buffer overflow in ovpn‑dco‑win version 2.8.0 allows local attackers to cause a system crash by sending too large packets to the remote peer when the AEAD tag appears at the end of the encrypted packet
CVE-2026-26284 1 Imagemagick 1 Imagemagick 2026-04-17 6.5 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, ImageMagick lacks proper boundary checking when processing Huffman-coded data from PCD (Photo CD) files. The decoder contains an function that has an incorrect initialization that could cause an out of bounds read. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-6296 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-17 9.6 Critical

CVE-2026-27820 1 Ruby 1 Zlib 2026-04-17 5.6 Medium
zlib is a Ruby interface for the zlib compression/decompression library. Versions 3.0.0 and below, 3.1.0, 3.1.1, 3.2.0 and 3.2.1 contain a buffer overflow vulnerability in the Zlib::GzipReader. The zstream_buffer_ungets function prepends caller-provided bytes ahead of previously produced output but fails to guarantee the backing Ruby string has enough capacity before the memmove shifts the existing data. This can lead to memory corruption when the buffer length exceeds capacity. This issue has been fixed in versions 3.0.1, 3.1.2 and 3.2.3.
CVE-2026-40396 2 Varnish-software, Vinyl-cache 2 Varnish Cache, Vinyl Cache 2026-04-17 4 Medium
Varnish Cache 9 before 9.0.1 allows a "workspace overflow" denial of service (daemon panic) after timeout_linger. A malicious client could send an HTTP/1 request, wait long enough until the session releases its worker thread (timeout_linger) and resume traffic before the session is closed (timeout_idle) sending more than one request at once to trigger a pipelining operation between requests. This vulnerability affecting Varnish Cache 9.0.0 emerged from a port of the Varnish Enterprise non-blocking architecture for HTTP/2. New code was needed to adapt to a more recent workspace API that formalizes the pipelining operation. In addition to the workspace change on the Varnish Cache side, other differences created merge conflicts, like partial support for trailers in Varnish Enterprise. The conflict resolution missed one code path configuring pipelining to perform a complete workspace rollback, losing the guarantee that prefetched data would fit inside workspace_client during the transition from one request to the next. This can result in a workspace overflow, triggering a panic and crashing the Varnish server.
CVE-2026-40394 2 Varnish-software, Vinyl-cache 3 Varnish Cache, Varnish Enterprise, Vinyl Cache 2026-04-17 4 Medium
Varnish Cache 9 before 9.0.1 and Varnish Enterprise before 6.0.16r11 allows a "workspace overflow" denial of service (daemon panic) for certain amounts of prefetched data. The setup of an HTTP/2 session starts with a speculative HTTP/1 transport, and upon upgrading to h2 the HTTP/1 request is repurposed as stream zero. During the upgrade, a buffer allocation is made to reserve space to send frames to the client. This allocation would split the original workspace, and depending on the amount of prefetched data, the next fetch could perform a pipelining operation that would run out of workspace.
CVE-2026-20049 1 Cisco 3 Adaptive Security Appliance Software, Firepower Threat Defense Software, Secure Firewall Threat Defense 2026-04-17 7.7 High
A vulnerability in the processing of Galois/Counter Mode (GCM)-encrypted Internet Key Exchange version 2 (IKEv2) IPsec traffic of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to the allocation of an insufficiently sized block of memory. An attacker could exploit this vulnerability by sending crafted GCM-encrypted IPsec traffic to an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition. To exploit this vulnerability, the attacker must have valid credentials to establish a VPN connection with the affected device.
CVE-2018-25244 1 Ecosearch 1 Eco Search 2026-04-16 6.2 Medium
Eco Search 1.0.2.0 contains a denial of service vulnerability that allows local attackers to crash the application by submitting an excessively long string to the search functionality. Attackers can paste a buffer of 950 or more characters into the search bar and trigger a crash by initiating a search operation.
CVE-2026-28686 1 Imagemagick 1 Imagemagick 2026-04-16 6.8 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, A heap-buffer-overflow vulnerability exists in the PCL encode due to an undersized output buffer allocation. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
