Improper Restriction of Operations within the Bounds of a Memory Buffer and Stack-based Buffer Overflow vulnerabilities were discovered in Apache NuttX RTOS Bluetooth Stack (HCI and UART components) that may result in system crash, denial of service, or arbitrary code execution, after receiving maliciously crafted packets.

NuttX's Bluetooth HCI/UART stack users are advised to upgrade to version 12.9.0, which fixes the identified implementation issues.

This issue affects Apache NuttX: from 7.25 before 12.9.0.

Apache Nuttx Versions prior to 10.1.0 are vulnerable to integer wrap-around in functions malloc, realloc and memalign. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

Out-of-bounds Write vulnerability in TCP Stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying and invalid fragmentation offset value specified in the IP header. This is only impacts builds with both CONFIGEXPERIMENTAL and CONFIGNETTCPREASSEMBLY build flags enabled.

Out-of-bounds Write vulnerability in TCP stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying arbitrary urgent data pointer offsets within TCP packets including beyond the length of the packet.

The Apache NuttX (Incubating) project provides an optional separate "apps" repository which contains various optional components and example programs. One of these, ftpd, had a NULL pointer dereference bug. The NuttX RTOS itself is not affected. Users of the optional apps repository are affected only if they have enabled ftpd. Versions 6.15 to 8.2 are affected.
