CVE-2026-29022 1 Mackron 1 Dr Libs 2026-03-23 7.3 High
dr_libs dr_wav.h version 0.14.4 and earlier (fixed in commit 8a7258c) contain a heap buffer overflow vulnerability in the drwav__read_smpl_to_metadata_obj() function of dr_wav.h that allows memory corruption via crafted WAV files. Attackers can exploit a mismatch between sampleLoopCount validation in pass 1 and unconditional processing in pass 2 to overflow heap allocations with 36 bytes of attacker-controlled data through any drwav_init_*_with_metadata() call on untrusted input.
CVE-2026-23750 1 Golioth 1 Pouch 2026-03-23 8.1 High
Golioth Pouch version 0.1.0, prior to commit 1b2219a1, contains a heap-based buffer overflow in BLE GATT server certificate handling. server_cert_write() allocates a heap buffer of size CONFIG_POUCH_SERVER_CERT_MAX_LEN when receiving the first fragment, then appends subsequent fragments using memcpy() without verifying that sufficient capacity remains. An adjacent BLE client can send unauthenticated fragments whose combined size exceeds the allocated buffer, causing a heap overflow and crash; integrity impact is also possible due to memory corruption.
CVE-2026-23747 1 Golioth 1 Firmware Sdk 2026-03-23 3.7 Low
Golioth Firmware SDK version 0.10.0 prior to 0.22.0, fixed in commit 48f521b, contain a stack-based buffer overflow in Payload Utils. The golioth_payload_as_int() and golioth_payload_as_float() helpers copy network-supplied payload data into fixed-size stack buffers using memcpy() with a length derived from payload_size. The only length checks are guarded by assert(); in release builds, the asserts are compiled out and memcpy() may copy an unbounded payload_size. Payloads larger than 12 bytes (int) or 32 bytes (float) can overflow the stack, resulting in a crash/denial of service. This is reachable via LightDB State on_payload with a malicious server or MITM.
CVE-2025-34523 1 Arcserve 1 Udp 2026-03-23 9.8 Critical
A heap-based buffer overflow vulnerability exists in the exists in the network-facing input handling routines of Arcserve Unified Data Protection (UDP). This flaw is reachable without authentication and results from improper bounds checking when processing attacker-controlled input. By sending specially crafted data, a remote attacker can corrupt heap memory, potentially causing a denial of service or enabling arbitrary code execution depending on the memory layout and exploitation techniques used. This vulnerability is similar in nature to CVE-2025-34522 but affects a separate code path or component. No user interaction is required, and exploitation occurs in the context of the vulnerable process. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue.
CVE-2025-34522 1 Arcserve 1 Udp 2026-03-23 9.8 Critical
A heap-based buffer overflow vulnerability exists in the input parsing logic of Arcserve Unified Data Protection (UDP). This flaw can be triggered without authentication by sending specially crafted input to the target system. Improper bounds checking allows an attacker to overwrite heap memory, potentially leading to application crashes or remote code execution. Exploitation occurs in the context of the affected process and does not require user interaction. The vulnerability poses a high risk due to its pre-authentication nature and potential for full compromise. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue.
CVE-2025-34468 1 Libcoap 1 Libcoap 2026-03-23 9.8 Critical
libcoap versions up to and including 4.3.5, prior to commit 30db3ea, contain a stack-based buffer overflow in address resolution when attacker-controlled hostname data is copied into a fixed 256-byte stack buffer without proper bounds checking. A remote attacker can trigger a crash and potentially achieve remote code execution depending on compiler options and runtime memory protections. Exploitation requires the proxy logic to be enabled (i.e., the proxy request handling code path in an application using libcoap).
CVE-2025-34457 1 Wb2osz 1 Dire Wolf 2026-03-23 7.5 High
wb2osz/direwolf (Dire Wolf) versions up to and including 1.8, prior to commit 694c954, contain a stack-based buffer overflow vulnerability in the function kiss_rec_byte() located in src/kiss_frame.c. When processing crafted KISS frames that reach the maximum allowed frame length (MAX_KISS_LEN), the function appends a terminating FEND byte without reserving sufficient space in the stack buffer. This results in an out-of-bounds write followed by an out-of-bounds read during the subsequent call to kiss_unwrap(), leading to stack memory corruption or application crashes. This vulnerability may allow remote unauthenticated attackers to trigger a denial-of-service condition.
CVE-2025-34451 1 Proxychains-ng Project 1 Proxychains-ng 2026-03-23 7.8 High
rofl0r/proxychains-ng versions up to and including 4.17 and prior to commit cc005b7 contain a stack-based buffer overflow vulnerability in the function proxy_from_string() located in src/libproxychains.c. When parsing crafted proxy configuration entries containing overly long username or password fields, the application may write beyond the bounds of fixed-size stack buffers, leading to memory corruption or crashes. This vulnerability may allow denial of service and, under certain conditions, could be leveraged for further exploitation depending on the execution environment and applied mitigations.
CVE-2025-34450 1 Rtl 433 Project 1 Rtl 433 2026-03-23 7.8 High
merbanan/rtl_433 versions up to and including 25.02 and prior to commit 25e47f8 contain a stack-based buffer overflow vulnerability in the function parse_rfraw() located in src/rfraw.c. When processing crafted or excessively large raw RF input data, the application may write beyond the bounds of a stack buffer, resulting in memory corruption or a crash. This vulnerability can be exploited to cause a denial of service and, under certain conditions, may be leveraged for further exploitation depending on the execution environment and available mitigations.
CVE-2025-34165 2 Netsupport, Netsupportsoftware 3 Netsupport Manager Agent, Netsupport Manager Client, Netsupport Manager 2026-03-23 N/A

CVE-2025-34164 2 Netsupport, Netsupportsoftware 3 Netsupport Manager Agent, Netsupport Manager Client, Netsupport Manager 2026-03-23 N/A
A heap-based buffer overflow vulnerability in NetSupport Manager 14.x versions prior to 14.12.0000 allows a remote, unauthenticated attacker to cause a denial of service (DoS) or execute arbitrary code.
CVE-2013-10068 3 Foxit, Foxit Software, Foxitsoftware 3 Reader, Reader, Foxit Reader 2026-03-23 N/A
Foxit Reader Plugin version 2.2.1.530, bundled with Foxit Reader 5.4.4.11281, contains a stack-based buffer overflow vulnerability in the npFoxitReaderPlugin.dll module. When a PDF file is loaded from a remote host, an overly long query string in the URL can overflow a buffer, allowing remote attackers to execute arbitrary code.
CVE-2013-10042 1 Freeftpd 1 Freeftpd 2026-03-23 9.8 Critical
A stack-based buffer overflow vulnerability exists in freeFTPd version 1.0.10 and earlier in the handling of the FTP PASS command. When an attacker sends a specially crafted password string, the application fails to validate input length, resulting in memory corruption. This can lead to denial of service or arbitrary code execution. Exploitation requires the anonymous user account to be enabled.
CVE-2012-10060 1 Sysax 1 Multi Server 2026-03-23 9.8 Critical
Sysax Multi Server versions prior to 5.55 contains a stack-based buffer overflow in its SSH service. When a remote attacker supplies an overly long username during authentication, the server copies the input to a fixed-size stack buffer without proper bounds checking. This allows remote code execution under the context of the service.
CVE-2010-20049 1 Leapware 1 Leapftp 2026-03-23 N/A
LeapFTP < 3.1.x contains a stack-based buffer overflow vulnerability in its FTP client parser. When the client receives a directory listing containing a filename longer than 528 bytes, the application fails to properly bound-check the input and overwrites the Structured Exception Handler (SEH) chain. This allows an attacker operating a malicious FTP server to execute arbitrary code on the victim’s machine when the file is listed or downloaded.
CVE-2010-10015 1 Aol 2 Aim, Aol 2026-03-23 N/A
AOL versions up to and including 9.5 includes an ActiveX control (Phobos.dll) that exposes a method called Import() via the Phobos.Playlist COM object. This method is vulnerable to a stack-based buffer overflow when provided with an excessively long string argument. Exploitation allows remote attackers to execute arbitrary code in the context of the user, but only when the malicious HTML file is opened locally, due to the control not being marked safe for scripting or initialization. AOL remains an active and supported brand offering services like AOL Mail and AOL Desktop Gold, but the legacy AOL 9.5 desktop software—specifically the version containing the vulnerable Phobos.dll ActiveX control—is long discontinued and no longer maintained.
