| CVE-2021-34704 | 1 Cisco | 2 Adaptive Security Appliance Software, Secure Firewall Threat Defense | 2026-08-11 | 7.1 HIGH | 8.6 HIGH |
| A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition. This vulnerability is due to improper input validation when parsing HTTPS requests. An attacker could exploit this vulnerability by sending a malicious HTTPS request to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. | |||||

| CVE-2026-11793 | 1 Redhat | 1 389 Directory Server | 2026-08-07 | N/A | 4.9 MEDIUM |
| A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only. | |||||
| CVE-2020-37121 | 2026-08-06 | N/A | 5.5 MEDIUM | ||
| CODE::BLOCKS 16.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler with crafted Unicode characters. Attackers can create a malicious text file with 1982 bytes of buffer and shellcode to trigger remote code execution. | |||||
| CVE-2026-11771 | 1 Openvpn | 1 Openvpn | 2026-08-05 | N/A | 7.5 HIGH |
| OpenVPN version 2.1.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows attackers via an off-by-one buffer write in the NTLM proxy authentication to potentially cause a crash via a crafted NTLM response from a malicious proxy server | |||||
| CVE-2026-50259 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-08-05 | N/A | 7.8 HIGH |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root. | |||||
| CVE-2026-50258 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-08-05 | N/A | 7.8 HIGH |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root. | |||||
| CVE-2026-50256 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-08-05 | N/A | 7.8 HIGH |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root. | |||||
| CVE-2024-39480 | 1 Linux | 1 Linux Kernel | 2026-08-04 | N/A | 8.4 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: kdb: Fix buffer overflow during tab-complete Currently, when the user attempts symbol completion with the Tab key, kdb will use strncpy() to insert the completed symbol into the command buffer. Unfortunately it passes the size of the source buffer rather than the destination to strncpy() with predictably horrible results. Most obviously if the command buffer is already full but cp, the cursor position, is in the middle of the buffer, then we will write past the end of the supplied buffer. Fix this by replacing the dubious strncpy() calls with memmove()/memcpy() calls plus explicit boundary checks to make sure we have enough space before we start moving characters around. | |||||
| CVE-2025-22457 | 1 Ivanti | 3 Connect Secure, Policy Secure, Zero Trust Access Gateway | 2026-08-04 | N/A | 9.0 CRITICAL |
| A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.6, Ivanti Policy Secure before version 22.7R1.4, and Ivanti ZTA Gateways before version 22.8R2.2 allows a remote unauthenticated attacker to achieve remote code execution. | |||||
| CVE-2024-10918 | 1 Libmodbus | 1 Libmodbus | 2026-08-01 | N/A | 4.8 MEDIUM |
| Stack-based Buffer Overflow vulnerability in libmodbus v3.1.10 allows to overflow the buffer allocated for the Modbus response if the function tries to reply to a Modbus request with an unexpected length. | |||||
| CVE-2026-16870 | 2026-07-30 | N/A | 8.8 HIGH | ||
| Multiple security vulnerabilities in Snowflake libsnowflakeclient versions prior to 2.9.2 could allow remote code execution and credential exfiltration. A stack-based buffer overflow in the file download path could allow remote code execution on a victim host. An attacker could exploit this by uploading a file with a crafted encryption metadata field to a shared internal stage that a victim process later downloads, and impact would be limited to deployments where principals with different privilege levels share the same internal stage. A related out-of-bounds write in the same download path could allow memory corruption with attacker-controlled write primitives. An attacker may exploit this through a crafted initialization vector metadata field on a shared stage, and impact would be limited by the same stage-write precondition. Improper validation of connection parameters could allow an attacker-controlled input to redirect outbound authentication requests — including credentials and tokens — to an attacker-controlled endpoint. Impact is limited to embedding deployments where a lower-privileged principal can influence connection configuration while higher-privileged service credentials are in use. The fix is available in Snowflake libsnowflakeclient version 2.9.2. The Snowflake PHP PDO Driver and Snowflake ODBC Driver embed the affected library; fixes are available in versions 4.1.0 and 3.19.0 respectively. Users must manually upgrade. | |||||
| CVE-2026-5056 | 2026-07-30 | N/A | 7.8 HIGH | ||
| GStreamer qtdemux Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of UncompressedFrameConfigBox structures. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29392. | |||||
