CVE-2018-25313 2 Flexense, Sysgauge 2 Sysgauge, Sysgauge 2026-05-01 6.2 Medium
SysGauge 4.5.18 contains a buffer overflow vulnerability in the proxy configuration handler that allows local attackers to cause a denial of service by supplying an oversized string. Attackers can inject a large payload through the Proxy Server Host Name field in the Options menu to crash the application.
CVE-2026-35547 1 Freebsd 1 Freebsd 2026-05-01 8.1 High
When processing the header of an incoming message, libnv failed to properly validate the message size. The lack of validation allows a malicious program to write outside the bounds of a heap allocation. This can trigger a crash or system panic, and it may be possible for an unprivileged user to exploit the bug to elevate their privileges.
CVE-2026-42512 1 Freebsd 1 Freebsd 2026-05-01 8.1 High
As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to overrun its buffer of environment entries. This can result in a crash, but it may be possible to leverage this bug to achieve remote code execution.
CVE-2026-33491 1 Zenc-lang 2 Zen C, Zenc 2026-05-01 7.8 High
Zen C is a systems programming language that compiles to human-readable GNU C/C11. Prior to version 0.4.4, a stack-based buffer overflow vulnerability in the Zen C compiler allows attackers to cause a compiler crash or potentially execute arbitrary code by providing a specially crafted Zen C source file (`.zc`) with excessively long struct, function, or trait identifiers. Users are advised to update to Zen C version v0.4.4 or later to receive a patch.
CVE-2026-40686 1 Exim 1 Exim 2026-05-01 3.7 Low
In Exim before 4.99.2, when utf8 operators are enabled, there is an out-of-bounds read if large UTF-8 trailing characters are present (malformed UTF-8 header data). Information might be divulged within an error message produced during handling of an unrelated e-mail message.
CVE-2026-41499 1 Wazuh 1 Wazuh 2026-05-01 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-2026-39457 1 Freebsd 1 Freebsd 2026-05-01 7.8 High
When exchanging data over a socket, libnv uses select(2) to wait for data to arrive. However, it does not verify whether the provided socket descriptor fits in select(2)'s file descriptor set size limit of FD_SETSIZE (1024). An attacker who is able to force a libnv application to allocate large file descriptors, e.g., by opening many descriptors and executing a program which is not careful to close them upon startup, can trigger stack corruption. If the target application is setuid-root, then this could be used to elevate local privileges.
CVE-2026-22828 1 Fortinet 4 Fortianalyzer Cloud, Fortianalyzercloud, Fortimanager Cloud and 1 more 2026-05-01 7.3 High
A heap-based buffer overflow vulnerability in Fortinet FortiAnalyzer Cloud 7.6.2 through 7.6.4, FortiManager Cloud 7.6.2 through 7.6.4 may allow a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests. Successful exploitation would require a large amount of effort in preparation because of ASLR and network segmentation
CVE-2026-26204 1 Wazuh 1 Wazuh 2026-04-30 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-2026-28221 1 Wazuh 1 Wazuh 2026-04-30 6.5 Medium
Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.8.0 to before version 4.14.4, a stack-based buffer overflow exists in print_hex_string() in wazuh-remoted. The bug is triggered when formatting attacker-controlled bytes using sprintf(dst_buf + 2*i, "%.2x", src_buf[i]) on platforms where char is treated as signed and the compiled code sign-extends bytes before the variadic call. For input bytes such as 0xFF, the formatting can emit "ffffffff" (8 chars) instead of "ff" (2 chars), causing an out-of-bounds write past a fixed 2049-byte stack buffer. The vulnerable path is reachable remotely prior to any agent authentication/registration logic via TCP/1514 when an oversized length prefix causes the “unexpected message (hex)” diagnostic path to run. Additionally, the same unauthenticated oversized-message diagnostic path logs an attacker-controlled hex dump to /var/ossec/logs/ossec.log for each trigger, allowing remote log amplification that can degrade monitoring fidelity and consume disk/I/O. This log amplification is reachable even without triggering the sign-extension overflow (e.g., using bytes < 0x80). This issue has been patched in version 4.14.4.
CVE-2025-59028 2 Dovecot, Open-xchange 3 Dovecot, Dovecot, Ox Dovecot Pro 2026-04-30 5.3 Medium
When sending invalid base64 SASL data, login process is disconnected from the auth server, causing all active authentication sessions to fail. Invalid BASE64 data can be used to DoS a vulnerable server to break concurrent logins. Install fixed version or disable concurrency in login processes (heavy perfomance penalty on large deployments). No publicly available exploits are known.
