Descripción técnica

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 18.7.11 and iPadOS 18.7.11, iOS 26.7.1 and iPadOS 26.7.1, macOS Sequoia 15.8.1, macOS Tahoe 26.7.1. Processing a maliciously crafted file may lead to arbitrary code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27.

——0BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.6, 1.5.2, and 1.6.1, the BACnet/SC message decoder walks the header-option list by following each option's MORE bit. Nothing rejects a list whose last option still has the MORE bit set, and the decode walk has no upper bound on how many options it processes. A single crafted BVLC-SC frame makes the walk advance one option past the end of the message and read message[message_len], one byte out of bounds. When the bytes after the message carry more MORE-set option markers, the walk keeps going: it runs past the fixed 4-entry option array and writes decoded option fields out of bounds. On the server that decode array is the static global bsc_dm, so the out-of-bounds write lands in adjacent BSS. Both faults are reachable before authentication, from the first frame a peer sends on a BACnet/SC connection, and the bytes that follow the message are the same peer's prior-frame data. This issue has been patched in versions 1.4.6, 1.5.2, 1.6.1, and 1.7.0.20h CVE-2026-824148.8 ALT

——0BACnet Stack is a BACnet open source protocol stack C library for embedded systems. From versions 1.4.0 to before 1.4.6, 1.5.0 to before 1.5.1, and 1.6.0 to before 1.6.1, the BACnet MS/TP receive path decodes COBS frames into an output pointer inside the same fixed input buffer, but passes the full input-buffer size as the decode capacity. A long valid COBS payload can therefore write past the end of the actual remaining buffer. This issue has been patched in versions 1.4.6, 1.5.1, 1.6.1, and 1.7.0.19h CVE-2026-97357—

——0C-Kermit 6.0.192 before 11.1.515 contains a buffer overflow vulnerability in tn_snenv() in ckctel.c that allows malicious Telnet servers to corrupt client memory via crafted NEW-ENVIRON SEND subnegotiation. Malicious or machine-in-the-middle servers can send oversized variable names before authentication, overflowing a 16-byte stack buffer and a miscomputed heap buffer to corrupt stack and heap memory.20h CVE-2026-584988.6 ALT

——0BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, there is a remote global-buffer-overflow in the official router-ipv6 application shipped with bacnet-stack, this results in an out-of-bounds write to the global transmit buffer under ASan. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.20h CVE-2026-52788—

——0BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, the bsc_node_parse_urls() function in src/bacnet/datalink/bsc/bsc-node.c contains three distinct bugs when parsing space-separated WebSocket URIs from a BACnet/SC Address Resolution ACK message. Two bugs cause out-of-bounds writes past the utf8_urls[10][129] array in the static BSC_ADDRESS_RESOLUTION structure. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.20h
