Stack-based Buffer Overflow

AGL agl-service-can-low-level contains a stack buffer overflow in the uds-c library. The send_diagnostic_request function in uds.c allocates a 6-byte stack buffer (MAX_DIAGNOSTIC_PAYLOAD_SIZE=6) but copies up to 7 bytes (MAX_UDS_REQUEST_PAYLOAD_LENGTH=7) via memcpy at an offset of 1+pid_length (2-3 bytes), resulting in 1-4 bytes of controlled stack overflow. The payload_length field (uint8_t) has no bounds check against the destination buffer. On 32-bit ARM automotive ECUs without stack canaries, this can lead to return address overwrite and RCE.Show less

Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_canswitch.cpp the parser does not properly validate a CANswitch DLC value, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted CANswitch frames.Show less

Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_pcap.cpp , the parser's phdr.len field is not properly validated, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted PCAP input.Show less

Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_gvret.cpp, the length field in GVRET binary data is not properly validated, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted GVRET frames.Show less

Buffer overflow vulnerability in cannelloni v2.0.0 in CAN frame parsing in parser.cpp in function parseCANFrame, and decoder.cpp in function decodeFrame allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted CAN FD frames.Show less

miaofng/uds-c commit e506334e270d77b20c0bc259ac6c7d8c9b702b7a (2016-10-05) contains a stack buffer overflow in send_diagnostic_request. A 6-byte stack buffer (MAX_DIAGNOSTIC_PAYLOAD_SIZE=6) receives memcpy at offset 1+pid_length with payload_length bytes. MAX_UDS_REQUEST_PAYLOAD_LENGTH=7, so 1+2+7=10 exceeds buffer by 4 bytes. No bounds check on payload_length before memcpy.Show less

AGL agl-service-can-low-level thru 17.1.12 contains a stack buffer overflow in the uds-c library. The send_diagnostic_request function in uds.c allocates a 6-byte stack buffer (MAX_DIAGNOSTIC_PAYLOAD_SIZE=6) but copies up to 7 bytes (MAX_UDS_REQUEST_PAYLOAD_LENGTH=7) via memcpy at an offset of 1+pid_length (2-3 bytes), resulting in 1-4 bytes of controlled stack overflow. The payload_length field (uint8_t) has no bounds check against the destination buffer. On 32-bit ARM automotive ECUs without stack canaries, this can lead to return address overwrite and RCE.Show less

A stack-based buffer overflow in mangle_to_hex_lower() and mangle_to_hex_upper() in src/rp_cpu.c in hashcat v7.1.2 allows an attacker to cause a denial of service or possibly execute arbitrary code via a crafted rule file, or via the -j or -k rule options used with password candidates of 128 or more characters. The vulnerability is caused by a bounds check that fails to account for the 2x expansion that occurs when password bytes are converted to hexadecimal.Show less

A security vulnerability has been detected in Totolink NR1800X 9.1.0u.6279_B20210910. The impacted element is the function find_host_ip of the component lighttpd. Such manipulation of the argument Host leads to stack-based buffer overflow. The attack can be executed remotely. The exploit has been disclosed publicly and may be used.Show less

CVE-2026-40950 is a buffer overflow vulnerability in the Secure Access server prior to 14.50. Attackers with control of a modified client can send a specially crafted message to the server and cause a denial of serviceShow less

CVE-2026-33449 is a buffer overflow in a message handling function of the Secure Access client prior to 14.50. Attackers with control of a modified server can send a cryptographically valid message to the client, overwriting a small portion of memory conceivably leading to a denial of service.Show less

CVE-2026-33447 is a buffer overflow in a message parsing function of the Secure Access client prior to 14.50. Attackers with control of a modified server can send a special packet that can overwrite a small portion of memory conceivably leading to memory corruption or denial of service.Show less

When exchanging data over a socket, libnv uses select(2) to wait for data to arrive. However, it does not verify whether the provided socket descriptor fits in select(2)'s file descriptor set size limit of FD_SETSIZE (1024). An attacker who is able to force a libnv application to allocate large file descriptors, e.g., by opening many descriptors and executing a program which is not careful to close them upon startup, can trigger stack corruption. If the target application is setuid-root, then this could be used to elevate local privileges.Show less
