CVE-2026-20214 Alta · 7.5 CWE-120 01/07/2026
ClamAV FSG File Format Processing Out-of-Bounds Memory Corruption Vulnerability
A vulnerability in the FSG file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in FSG files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains portable executable content compressed with FSG to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20213 Alta · 7.5 CWE-120 01/07/2026
ClamAV PE File Format Processing Out-of-Bounds Memory Corruption Vulnerability
A vulnerability in the PE file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in PE files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains PE content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-6688 Alta · 7.6 CWE-120 01/07/2026
FatFs Buffer Overflow via Unbounded LFN Filename Copy
FatFs R0.16 and earlier contains a downstream-caller vulnerability pattern associated with FatFs long filename handling. With LFN enabled, fno.fname can be up to 255 characters; many callers copy it into short fixed buffers without bounds checks, causing overflow. This maps to CWE-120 (Buffer Copy without Checking Size of Input). Estimated CVSS v3.1 vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H (7.6, High). The estimated CISA SSVC vectors are Exploitation: PoC, Technical Impact: Total.

CVE-2026-48706 Alta · 7.5 CWE-120 26/06/2026
Envoy Heap Buffer Overflow in TcpStatsdSink
Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.34.0 until 1.35.13, 1.36.9, 1.37.5, and 1.38.3, a vulnerability exists in Envoy's TCP StatsD sink (TcpStatsdSink), where the thread-local flusher buffer can be overflowed by exceptionally long statistic names (e.g., >16KiB). During formatting, TcpStatsdSink reserves a single contiguous memory slice of 16KiB (FLUSH_SLICE_SIZE_BYTES). If formatting a single metric exceeds the remaining capacity, the flusher initiates a buffer rotation but incorrectly continues to allocate another fixed 16KiB slice. If an attacker can trigger a statistic name longer than 16KiB—for example, by sending an HTTP or gRPC request with an extremely long request path (:path) that is recorded by the grpc_stats filter configured with stats_for_all_methods: true—the flusher will attempt to copy the metric name using memcpy operations beyond the allocated heap buffer boundaries. This leads to a heap write overflow, which can cause immediate denial-of-service (process crash) or potential remote code execution (RCE). This vulnerability is fixed in 1.35.13, 1.36.9, 1.37.5, and 1.38.3.
CVE-2026-57874 Alta · 7.5 CWE-120 26/06/2026
GV-LPC2011/LPC2211 - unauthorized buffer overflow vulnerability (IEEE8021x_upload.cgi)
An unauthenticated buffer overflow vulnerability exists in IEEE8021x_upload.cgi in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when parsing filename values in multipart upload data. A remote attacker may exploit this vulnerability by sending a crafted upload request with overly long input, causing memory corruption and resulting in a denial of service.
CVE-2026-6681 Média · 5.3 CWE-120 25/06/2026
PKCS#7 decode ignores caller output buffer size, writing past buffer bounds
The PKCS#7 decode path ignores the caller-supplied output buffer size (outputSz), allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release.
CVE-2026-42450 Alta · 8.4 CWE-120 24/06/2026
OpenColorIO vulnerable to stack buffer overflow via unbounded `sscanf %s` in Spi3D (.spi3d) LUT parser
OpenColorIO is a color management framework for visual effects and animation. Prior to version 2.5.2, `FileFormatSpi3D.cpp:163` uses `sscanf` with `%s` into 64-byte stack buffers when parsing LUT data lines. Input comes from `lineBuffer[4096]`, so a crafted .spi3d file can overflow by ~4000 bytes on non-Windows. Version 2.5.2 fixes the issue.
CVE-2026-54257 Crítica · 9.3 CWE-120 23/06/2026
Electron: estouro de heap no Buffer por cálculo incorreto de tamanho em bytes
Electron é um framework para criar aplicações desktop multiplataforma usando JavaScript, HTML e CSS. Da 42.3.1 até a 42.3.3, o Buffer realiza cálculos incorretos de tamanho em bytes, resultando em underflow ou overflow de buffer na heap. A maioria dos aplicativos irá travar e alguns podem realizar alocações de buffer incorretas na API Buffer do Node.js, resultando em truncamento ou alocação inesperados. Esta vulnerabilidade está corrigida na 42.3.3.
CVE-2026-43994 Crítica · 9.8 CWE-120 18/06/2026
Estouro de buffer na pilha em tokens OAuth do Coturn em decode_oauth_token_gcm() (CVE-2026-43994)
Coturn é uma implementação livre e de código aberto de servidor TURN e STUN. Versões anteriores à 4.10.0 contêm um estouro de buffer na pilha em decode_oauth_token_gcm(). Um campo uint16_t nonce_len lido de um token de acesso OAuth fornecido pelo atacante (0-65535) é passado diretamente ao memcpy() como tamanho da cópia para um buffer de pilha de 256 bytes (oauth_encrypted_block.nonce[256]) sem verificação de limites. O estouro ocorre antes de a autenticação AES-GCM ser verificada; o atacante não precisa conhecer a chave OAuth nem produzir um token AES-GCM válido. Até 735 bytes de dados controlados pelo atacante são gravados além do buffer, podendo corromper dados adjacentes da pilha, incluindo dados de fluxo de controle, dependendo do compilador, da ABI e das mitigações. Requer o modo --oauth (não padrão). Isso pode fornecer uma primitiva plausível de RCE, dependendo das mitigações contra exploração; como o coturn é amplamente implantado para TURN/STUN em WebRTC e o --oauth é comumente recomendado, o impacto pode ser amplo. Este problema foi corrigido na versão 4.10.0.
