CVE-2026-0648 Média · 6.3 CWE-787 27/01/2026
Out-of-bounds Write em Eclipse Foundation Threadx
The vulnerability stems from an incorrect error-checking logic in the CreateCounter() function (in threadx/utility/rtos_compatibility_layers/OSEK/tx_osek.c) when handling the return value of osek_get_counter(). Specifically, the current code checks if cntr_id equals 0u to determine failure, but @osek_get_counter() actually returns E_OS_SYS_STACK (defined as 12U) when it fails. This mismatch causes the error branch to never execute even when the counter pool is exhausted. As a result, when the counter pool is depleted, the code proceeds to cast the error code (12U) to a pointer (OSEK_COUNTER *), creating a wild pointer. Subsequent writes to members of this pointer lead to writes to illegal memory addresses (e.g., 0x0000000C), which can trigger immediate HardFaults or silent memory corruption. This vulnerability poses significant risks, including potential denial-of-service attacks (via repeated calls to exhaust the counter pool) and unauthorized memory access.
CVE-2025-69419 Alta · 7.4 CWE-787 27/01/2026
Out of bounds write in PKCS12_get_friendlyname() UTF-8 conversion
Issue summary: Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption which can have various consequences including a Denial of Service. The OPENSSL_uni2utf8() function performs a two-pass conversion of a PKCS#12 BMPString (UTF-16BE) to UTF-8. In the second pass, when emitting UTF-8 bytes, the helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16 source byte count as the destination buffer capacity to UTF8_putc(). For BMP code points above U+07FF, UTF-8 requires three bytes, but the forwarded capacity can be just two bytes. UTF8_putc() then returns -1, and this negative value is added to the output length without validation, causing the length to become negative. The subsequent trailing NUL byte is then written at a negative offset, causing write outside of heap allocated buffer. The vulnerability is reachable via the public PKCS12_get_friendlyname() API when parsing attacker-controlled PKCS#12 files. While PKCS12_parse() uses a different code path that avoids this issue, PKCS12_get_friendlyname() directly invokes the vulnerable function. Exploitation requires an attacker to provide a malicious PKCS#12 file to be parsed by the application and the attacker can just trigger a one zero byte write before the allocated buffer. For that reason the issue was assessed as Low severity according to our Security Policy. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue. OpenSSL 1.0.2 is not affected by this issue.
CVE-2025-68670 Crítica · 9.8 CWE-787 27/01/2026
Estouro de buffer baseado em pilha no servidor RDP xrdp (CVE-2025-68670)
xrdp é um servidor RDP de código aberto. O xrdp anterior à v0.10.5 contém uma vulnerabilidade de estouro de buffer baseado em pilha (stack-based buffer overflow) não autenticada. O problema decorre de verificação inadequada de limites ao processar informações de domínio do usuário durante a sequência de conexão. Se explorada, a vulnerabilidade poderia permitir que atacantes remotos executassem código arbitrário no sistema alvo. A vulnerabilidade permite que um atacante sobrescreva o buffer na pilha e o endereço de retorno, o que, teoricamente, poderia ser usado para redirecionar o fluxo de execução. O impacto desta vulnerabilidade é reduzido se uma flag do compilador tiver sido usada para compilar o executável do xrdp com proteção por canário de pilha (stack canary). Nesse caso, uma segunda vulnerabilidade precisaria ser usada para vazar o valor do canário de pilha. Atualize para a versão 0.10.5 para receber a correção. Além disso, não dependa da proteção por canário de pilha em sistemas de produção.
CVE-2025-68160 Média · 4.7 CWE-787 27/01/2026
Heap out-of-bounds write in BIO_f_linebuffer on short writes
Issue summary: Writing large, newline-free data into a BIO chain using the line-buffering filter where the next BIO performs short writes can trigger a heap-based out-of-bounds write. Impact summary: This out-of-bounds write can cause memory corruption which typically results in a crash, leading to Denial of Service for an application. The line-buffering BIO filter (BIO_f_linebuffer) is not used by default in TLS/SSL data paths. In OpenSSL command-line applications, it is typically only pushed onto stdout/stderr on VMS systems. Third-party applications that explicitly use this filter with a BIO chain that can short-write and that write large, newline-free data influenced by an attacker would be affected. However, the circumstances where this could happen are unlikely to be under attacker control, and BIO_f_linebuffer is unlikely to be handling non-curated data controlled by an attacker. For that reason the issue was assessed as Low severity. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the BIO implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.
CVE-2025-55095 Alta · 7.0 CWE-787 27/01/2026
Out-of-bounds Write em Eclipse Foundation Threadx Usbx
The function _ux_host_class_storage_media_mount() is responsible for mounting partitions on a USB mass storage device. When it encounters an extended partition entry in the partition table, it recursively calls itself to mount the next logical partition. This recursion occurs in _ux_host_class_storage_partition_read(), which parses up to four partition entries. If an extended partition is found (with type UX_HOST_CLASS_STORAGE_PARTITION_EXTENDED or EXTENDED_LBA_MAPPED), the code invokes: _ux_host_class_storage_media_mount(storage, sector + _ux_utility_long_get(...)); There is no limit on the recursion depth or tracking of visited sectors. As a result, a malicious or malformed disk image can include cyclic or excessively deep chains of extended partitions, causing the function to recurse until stack overflow occurs.
CVE-2025-15467 Alta · 8.8 CWE-787 27/01/2026
Stack buffer overflow in CMS (Auth)EnvelopedData parsing
Issue summary: Parsing CMS AuthEnvelopedData or EnvelopedData message with maliciously crafted AEAD parameters can trigger a stack buffer overflow. Impact summary: A stack buffer overflow may lead to a crash, causing Denial of Service, or potentially remote code execution. When parsing CMS (Auth)EnvelopedData structures that use AEAD ciphers such as AES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters is copied into a fixed-size stack buffer without verifying that its length fits the destination. An attacker can supply a crafted CMS message with an oversized IV, causing a stack-based out-of-bounds write before any authentication or tag verification occurs. Applications and services that parse untrusted CMS or PKCS#7 content using AEAD ciphers (e.g., S/MIME (Auth)EnvelopedData with AES-GCM) are vulnerable. Because the overflow occurs prior to authentication, no valid key material is required to trigger it. While exploitability to remote code execution depends on platform and toolchain mitigations, the stack-based write primitive represents a severe risk. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4, 3.3 and 3.0 are vulnerable to this issue. OpenSSL 1.1.1 and 1.0.2 are not affected by this issue.
