| CVE-2008-2719 | 1 Nasm | 1 Netwide Assembler | 2026-04-23 | N/A |
| Off-by-one error in the ppscan function (preproc.c) in Netwide Assembler (NASM) 2.02 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted file that triggers a stack-based buffer overflow. | ||||
| CVE-2006-4574 | 2 Redhat, Wireshark | 2 Enterprise Linux, Wireshark | 2026-04-23 | 7.5 High |
| Off-by-one error in the MIME Multipart dissector in Wireshark (formerly Ethereal) 0.10.1 through 0.99.3 allows remote attackers to cause a denial of service (crash) via certain vectors that trigger an assertion error related to unexpected length values. | ||||
| CVE-2025-71237 | 1 Linux | 1 Linux Kernel | 2026-04-20 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nilfs2: Fix potential block overflow that cause system hang When a user executes the FITRIM command, an underflow can occur when calculating nblocks if end_block is too small. Since nblocks is of type sector_t, which is u64, a negative nblocks value will become a very large positive integer. This ultimately leads to the block layer function __blkdev_issue_discard() taking an excessively long time to process the bio chain, and the ns_segctor_sem lock remains held for a long period. This prevents other tasks from acquiring the ns_segctor_sem lock, resulting in the hang reported by syzbot in [1]. If the ending block is too small, typically if it is smaller than 4KiB range, depending on the usage of the segment 0, it may be possible to attempt a discard request beyond the device size causing the hang. Exiting successfully and assign the discarded size (0 in this case) to range->len. Although the start and len values in the user input range are too small, a conservative strategy is adopted here to safely ignore them, which is equivalent to a no-op; it will not perform any trimming and will not throw an error.

| CVE-2026-21490 | 2 Color, Internationalcolorconsortium | 2 Iccdev, Iccdev | 2026-04-18 | 6.1 Medium |
| iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. A vulnerability present in versions prior to 2.3.1.2 affects users of the iccDEV library who process ICC color profiles. It results in heap buffer overflow in `CIccTagLut16::Validate()`. Version 2.3.1.2 contains a patch. No known workarounds are available. | ||||
| CVE-2026-23951 | 1 Sumatrapdfreader | 1 Sumatrapdf | 2026-04-18 | 5.5 Medium |
| SumatraPDF is a multi-format reader for Windows. All versions contain an off-by-one error in the validation code that only triggers with exactly 2 records, causing an integer underflow in the size calculation. This bug exists in PalmDbReader::GetRecord when opening a crafted Mobi file, resulting in an out-of-bounds heap read that crashes the app. There are no published fixes at the time of publication. | ||||

Version 2.3.1.2 contains a patch. No known workarounds are available. | ||||
| CVE-2026-21491 | 2 Color, Internationalcolorconsortium | 2 Iccdev, Iccdev | 2026-04-18 | 6.1 Medium |
| iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. A vulnerability present in versions prior to 2.3.1.2 affects users of the iccDEV library who process ICC color profiles. It results in unicode buffer overflow in `CIccTagTextDescription`. Version 2.3.1.2 contains a patch. No known workarounds are available. | ||||
| CVE-2026-40312 | 1 Imagemagick | 1 Imagemagick | 2026-04-17 | 6.2 Medium |
| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-19, an off by one error in the MSL decoder could result in a crash when a malicous MSL file is read. This issue has been fixed in version 7.1.2-19. | ||||
| CVE-2026-21870 | 1 Bacnetstack | 1 Bacnet Stack | 2026-04-17 | 5.5 Medium |
| BACnet Protocol Stack library provides a BACnet application layer, network layer and media access (MAC) layer communications services. In 1.4.2, 1.5.0.rc2, and earlier, an off-by-one stack-based buffer overflow in the ubasic interpreter causes a crash (SIGABRT) when processing string literals longer than the buffer limit. The tokenizer_string function in src/bacnet/basic/program/ubasic/tokenizer.c incorrectly handles null termination for maximum-length strings. It writes a null byte to dest[40] when the buffer size is only 40 (indices 0-39), triggering a stack overflow. | ||||
| CVE-2026-2703 | 1 Xlnt-community | 1 Xlnt | 2026-04-17 | 3.3 Low |
| A weakness has been identified in xlnt-community xlnt up to 1.6.1. Impacted is the function xlnt::detail::decode_base64 of the file source/detail/cryptography/base64.cpp of the component Encrypted XLSX File Parser. Executing a manipulation can lead to off-by-one. The attack requires local access. The exploit has been made available to the public and could be used for attacks. This patch is called f2d7bf494e5c52706843cf7eb9892821bffb0734. Applying a patch is advised to resolve this issue. | ||||
| CVE-2026-25989 | 1 Imagemagick | 1 Imagemagick | 2026-04-16 | 7.5 High |
| 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, a crafted SVG file can cause a denial of service. An off-by-one boundary check (`>` instead of `>=`) that allows bypass the guard and reach an undefined `(size_t)` cast. Versions 7.1.2-15 and 6.9.13-40 contain a patch. | ||||
| CVE-2026-26309 | 1 Envoyproxy | 1 Envoy | 2026-04-16 | 5.3 Medium |
| Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, an off-by-one write in Envoy::JsonEscaper::escapeString() can corrupt std::string null-termination, causing undefined behavior and potentially leading to crashes or out-of-bounds reads when the resulting string is later treated as a C-string. This vulnerability is fixed in 1.37.1, 1.36.5, 1.35.8, and 1.34.13. | ||||
| CVE-2002-1745 | 1 Microsoft | 1 Internet Information Services | 2026-04-16 | 7.5 High |
| Off-by-one error in the CodeBrws.asp sample script in Microsoft IIS 5.0 allows remote attackers to view the source code for files with extensions containing with one additional character after .html, .htm, .asp, or .inc, such as .aspx files. | ||||
