Substance3D - Stager | Stack-based Buffer Overflow (CWE-121)

Substance3D - Stager is affected by a Stack-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

CVE-2026-9669

bz2.BZ2Decompressor reuse after error can cause a stack buffer overflow

bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data.

CVE-2026-109833

Gnome-remote-desktop: heap buffer overflow in gnome-remote-desktop vnc tls peek buffer handling allows remote denial of service

A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS read path, partial consumption of the internal peek buffer incorrectly moves remaining peeked bytes into the caller-supplied buffer instead of compacting the peek buffer. A remote attacker who can reach an enabled VNC TLS listener and trigger a peek/read size mismatch can cause an out-of-bounds write, leading to denial of service.

Netcore NR256CN through 1.5.140116 Pre-Auth Stack Overflow via Boa user_ok()

Netcore NR256CN through 1.5.140116 contains a pre-authentication stack overflow vulnerability in the Boa web server's user_ok() function, which copies Basic-auth usernames with unbounded strcpy() calls into 64-byte stack buffers. Unauthenticated attackers can send a username longer than 63 bytes to any protected /router/*.cgi route to crash the main Boa process or potentially execute code.

CVE-2026-123203

NEURON through 9.0.2 Stack-based Buffer Overflow via CoreNEURON dataset tokens

NEURON (CoreNEURON) through 9.0.2 contains a stack buffer overflow vulnerability that allows attackers to corrupt stack memory by supplying over-long tokens in a crafted model dataset. Attackers can place oversized version or mechanism-name tokens in bbcore_mech.dat, globals.dat, or files.dat loaded by nrniv-core to crash the process.

Gdb: gdb: stack buffer overflow in parse_tracepoint_definition via stale rs->buf tail

A stack buffer overflow in the GDB client's tracepoint upload handler allows an attacker-controlled debug stub to corrupt stack memory automatically during connection setup. The overflow results from GDB reading beyond the current reply boundary into a stale prior reply in the shared packet buffer.

SDL_mixer 3.1.2 through 3.2.4 Stack-based Buffer Overflow via FetchXLaw() in AIFF Decoder

SDL_mixer 3.1.2 through 3.2.4 contains a stack-based buffer overflow in FetchXLaw() in src/decoder_aiff.c due to miscalculated output offsets when expanding A-law or mu-law samples. Attackers can supply a crafted AIFF-C file that overwrites roughly 1 KB of adjacent stack memory when decoded, causing crashes or potential code execution.

SDL_mixer 3.1.2 through 3.2.4 Stack-based Buffer Overflow via FetchXLaw() in WAV Decoder

SDL_mixer 3.1.2 through 3.2.4 contains a stack-based buffer overflow vulnerability in FetchXLaw() of src/decoder_wav.c when decoding A-law or mu-law WAV files. Attackers can supply a crafted WAV file whose doubly-offset float expansion overwrites about 1 KB of adjacent stack memory, causing crashes or potentially code execution.

TOTOLINK A950RG Easy Setup Wizard cstecgi.cgi setAppEasyWizardConfig stack-based overflow

A weakness has been identified in TOTOLINK A950RG 4.1.2cu.5268_B20221104. This affects the function setAppEasyWizardConfig of the file /cgi-bin/cstecgi.cgi of the component Easy Setup Wizard Handler. Executing a manipulation of the argument functionType can lead to stack-based buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks.

ESP-IDF: Stack-based memory corruption in lwIP DNS/SNTP handling for multi-IP DNS responses

ESP-IDF is the Espressif Internet of Things (IOT) Development Framework. From 5.2.3 until 5.3.7, 5.4.5, 5.5.6, and 6.0.3, the lwIP DNS resolver's cached-lookup path in dns_lookup() in dns.c copies every cached address into a caller-provided single ip_addr_t output buffer without a length parameter or bounds check. When CONFIG_LWIP_DNS_MAX_HOST_IP is greater than 1 and a cached hostname has multiple A or AAAA records, a subsequent lookup through dns_gethostbyname() or dns_gethostbyname_addrtype() writes beyond the single-element buffer into adjacent stack memory. A network-positioned attacker who influences DNS responses can cause a reboot through stack-canary corruption or, without stack protection, overwrite stack variables with attacker-controlled address bytes and potentially redirect control flow. This issue is fixed in versions 5.5.6 and 6.0.3 and is scheduled to be fixed in versions 5.3.7 and 5.4.5. No fixed release is available for the end-of-life 5.2 line.

ESP-IDF: Stack-Based Out-of-Bounds Write in Thread Border Router ND6 Option Parsing

ESP-IDF is the Espressif Internet of Things (IOT) Development Framework. From 5.2.0 until 5.2.8, 5.3.6, 5.4.5, 5.5.5, and 6.0.3, the OpenThread Border Router Neighbor Discovery packet handler trusts an attacker-controlled ICMPv6 option length while copying into a fixed stack buffer. A host on the same infrastructure link as the Border Router can send a crafted ICMPv6 Router Advertisement to its infrastructure interface whose oversized length causes an out-of-bounds write into adjacent stack memory. Firmware is affected only when CONFIG_OPENTHREAD_BORDER_ROUTER=y; Thread end devices, routers, and RCP firmware without the Border Router feature are unaffected. Exploitation requires no authentication or user interaction and can crash or reboot the device or corrupt adjacent stack state. This issue is fixed in versions 5.2.8, 5.3.6, 5.5.5, and 6.0.3 and is scheduled to be fixed in version 5.4.5.
