| CVE-2026-24682 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, audin_server_recv_formats frees an incorrect number of audio formats on parse failure (i + i), leading to out-of-bounds access in audio_formats_free. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-26200 | 1 Hdfgroup | 1 Hdf5 | 2026-04-18 | 7.8 High |
| HDF5 is software for managing data. Prior to version 1.14.4-2, an attacker who can control an `h5` file parsed by HDF5 can trigger a write-based heap buffer overflow condition. This can lead to a denial-of-service condition, and potentially further issues such as remote code execution depending on the practical exploitability of the heap overflow against modern operating systems. Real-world exploitability of this issue in terms of remote-code execution is currently unknown. Version 1.14.4-2 fixes the issue. | ||||
| CVE-2026-2047 | 1 Gimp | 1 Gimp | 2026-04-18 | 7.8 High |
| GIMP ICNS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of ICNS files. 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-28530. | ||||
| CVE-2026-22791 | 3 Ibm, Linux, Opencryptoki Project | 3 Aix, Linux, Opencryptoki | 2026-04-18 | 6.6 Medium |
| openCryptoki is a PKCS#11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap buffer overflow vulnerability in the CKM_ECDH_AES_KEY_WRAP implementation allows an attacker with local access to cause out-of-bounds writes in the host process by supplying a compressed EC public key and invoking C_WrapKey. This can lead to heap corruption, or denial-of-service. | ||||
| CVE-2026-1188 | 1 Eclipse | 1 Omr | 2026-04-18 | 9.8 Critical |
| In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. If the output buffer supplied to this function was incorrectly sized, failing to account for the separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue is fixed in Eclipse OMR version 0.8.0. | ||||
| CVE-2026-24684 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, the RDPSND async playback thread can process queued PDUs after the channel is closed and internal state is freed, leading to a use after free in rdpsnd_treat_wave. This vulnerability is fixed in 3.22.0. | ||||
| 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 |
| Heap buffer overflow in ANGLE in Google Chrome prior to 147.0.7727.101 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: 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-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.

| CVE-2004-0434 | 2 Debian, Heimdal Project | 2 Debian Linux, Heimdal | 2026-04-16 | 9.8 Critical |
| k5admind (kadmind) for Heimdal allows remote attackers to execute arbitrary code via a Kerberos 4 compatibility administration request whose framing length is less than 2, which leads to a heap-based buffer overflow. | ||||
| CVE-2002-1347 | 3 Apple, Cyrusimap, Redhat | 4 Mac Os X, Mac Os X Server, Cyrus Sasl and 1 more | 2026-04-16 | 9.8 Critical |
| Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string. | ||||
| CVE-2003-0899 | 1 Acme | 1 Thttpd | 2026-04-16 | 9.8 Critical |
| Buffer overflow in defang in libhttpd.c for thttpd 2.21 to 2.23b1 allows remote attackers to execute arbitrary code via requests that contain '<' or '>' characters, which trigger the overflow when the characters are expanded to "<" and ">" sequences. | ||||
| CVE-2002-0184 | 3 Debian, Redhat, Sudo Project | 4 Debian Linux, Linux, Powertools and 1 more | 2026-04-16 | 7.8 High |
