| CVE-2026-16439 | 2026-07-21 | N/A | N/A | ||
| In Eclipse OpenJ9 versions up to 0.60, using -Xtrace to trace method arguments can lead to buffer underflow. | |||||
| CVE-2026-26199 | 2026-07-20 | N/A | N/A | ||
| HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If `H5Iget_name` is invoked on a group id with `0` for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if `H5Iget_name` is invoked in a way where `size` can be forced to zero, and there is important data before the `name` buffer. | |||||
| CVE-2025-4373 | 2026-07-19 | N/A | 4.8 MEDIUM | ||
| A flaw was found in GLib, which is vulnerable to an integer overflow in the g_string_insert_unichar() function. When the position at which to insert the character is large, the position will overflow, leading to a buffer underwrite. | |||||
| CVE-2026-34253 | 2026-07-15 | N/A | 8.2 HIGH | ||
| A buffer underflow vulnerability has been identified in the ogg123 utility from the vorbis-tools 1.4.3 package in function remotethread in remote.c. This vulnerability occurs in the remote control functionality when processing malformed input, leading to a stack buffer underflow that can cause application crashes and potentially allow code execution. | |||||
| CVE-2026-5089 | 2026-06-17 | N/A | 7.3 HIGH | ||
| YAML::Syck versions before 1.38 for Perl has an out-of-bounds read. The base60 (sexagesimal) parsing code in perl_syck.h has a buffer underflow bug in both int#base60 and float#base60 handlers. When processing the leftmost segment of a colon-separated value (e.g., the 1 in 1:30:45), the inner while loop can decrement a pointer past the start of the string buffer: while ( colon >= ptr && *colon != ':' ) { colon--; } if ( *colon == ':' ) *colon = '\0'; // colon may be ptr-1 here When no colon is found (final/leftmost segment), colon becomes ptr-1, and the subsequent *colon dereference reads one byte before the allocated buffer. | |||||
| CVE-2026-44631 | 1 Apache | 1 Http Server | 2026-06-17 | N/A | 9.8 CRITICAL |
| Buffer Underwrite vulnerability in Apache HTTP Server on crafted regular expressions in the configuration. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67. Users are recommended to upgrade to version 2.4.68, which fixes the issue. | |||||
| CVE-2026-41499 | 1 Wazuh | 1 Wazuh | 2026-06-17 | N/A | 6.5 MEDIUM |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.0.0 to before version 4.14.4, multiple heap-based out-of-bounds WRITE vulnerabilities exist in parse_uname_string() (remoted_op.c). This function processes OS identification data from agents and contains a dangerous code pattern that appears in 4 locations within the same function: writing to strlen(ptr) - 1 without checking for empty strings. When the string is empty, strlen() returns 0, and 0 - 1 wraps to SIZE_MAX due to unsigned integer underflow. Due to pointer arithmetic wrapping, SIZE_MAX effectively becomes -1, causing a write exactly 1 byte before the allocated buffer. This corrupts heap metadata (e.g., the chunk size field in glibc malloc), leading to heap corruption. This issue has been patched in version 4.14.4. | |||||
| CVE-2026-28419 | 1 Vim | 1 Vim | 2026-06-17 | N/A | 5.3 MEDIUM |
| Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue. | |||||
| CVE-2026-26204 | 1 Wazuh | 1 Wazuh | 2026-06-17 | N/A | 4.4 MEDIUM |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 1.0.0 to before version 4.14.4, a heap-based out-of-bounds WRITE occurs in GetAlertData, resulting in writing a NULL byte exactly 1 byte before the start of the buffer allocated by strdup. Due to unsigned integer underflow and pointer arithmetic wrapping, the write lands at offset -1 from the buffer, corrupting heap metadata. A malicious actor can potentially leverage this issue through a compromised agent to cause denial of service or heap corruption by injecting a specially crafted alert into the alerts log file monitored by wazuh-logcollector. This issue has been patched in version 4.14.4. | |||||
| CVE-2026-20104 | 2026-06-17 | N/A | 6.1 MEDIUM | ||
| A vulnerability in the bootloader of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches, Cisco Catalyst ESS9300 Embedded Series Switches, Cisco Catalyst IE9310 and IE9320 Rugged Series Switches, and Cisco IE3500 and IE3505 Rugged Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to an affected device to execute arbitrary code at boot time and break the chain of trust. This vulnerability is due to insufficient validation of software at boot time. An attacker could exploit this vulnerability by manipulating the loaded binaries on an affected device to bypass some of the integrity checks that are performed during the boot process. A successful exploit could allow the attacker to execute code that bypasses the requirement to run Cisco-signed images. Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates because this vulnerability allows an attacker to bypass a major security feature of a device. | |||||
| CVE-2026-1485 | 2026-06-17 | N/A | 2.8 LOW | ||
| A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability. | |||||
| CVE-2026-0966 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-06-17 | N/A | 8.2 HIGH |
| A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process. | |||||
| CVE-2025-68114 | 1 Capstone-engine | 1 Capstone | 2026-06-17 | N/A | 4.8 MEDIUM |
| Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue. | |||||
| CVE-2025-62786 | 1 Wazuh | 1 Wazuh | 2026-06-17 | N/A | 8.1 HIGH |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2. | |||||
| CVE-2025-61915 | 2 Opengroup, Openprinting | 2 Unix, Cups | 2026-06-17 | N/A | 6.0 MEDIUM |
| OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.15, a user in the lpadmin group can use the cups web ui to change the config and insert a malicious line. Then the cupsd process which runs as root will parse the new config and cause an out-of-bound write. This issue has been patched in version 2.4.15. | |||||
| CVE-2025-61690 | 2026-06-17 | N/A | 7.8 HIGH | ||
| KV STUDIO versions 12.23 and prior contain a buffer underflow vulnerability. If the product uses a specially crafted file, arbitrary code may be executed on the affected product. | |||||
| CVE-2025-53101 | 1 Imagemagick | 1 Imagemagick | 2026-06-17 | N/A | 7.4 HIGH |
| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-0 and 6.9.13-26, in ImageMagick's `magick mogrify` command, specifying multiple consecutive `%d` format specifiers in a filename template causes internal pointer arithmetic to generate an address below the beginning of the stack buffer, resulting in a stack overflow through `vsnprintf()`. Versions 7.1.2-0 and 6.9.13-26 fix the issue. | |||||
| CVE-2025-27440 | 1 Zoom | 6 Meeting Software Development Kit, Rooms, Rooms Controller and 3 more | 2026-06-17 | N/A | 8.5 HIGH |
| Heap overflow in some Zoom Workplace Apps may allow an authenticated user to conduct an escalation of privilege via network access. | |||||
