Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability was discovered in Apache NuttX RTOS apps/exapmles/xmlrpc application. In this example application device stats structure that stored remotely provided parameters had hardcoded buffer size which could lead to buffer overflow. Structure members buffers were updated to valid size of CONFIG_XMLRPC_STRINGSIZE+1.
This issue affects Apache NuttX RTOS users that may have used or base their code on example application as presented in releases from 6.22 before 12.9.0.
Users of XMLRPC in Apache NuttX RTOS are advised to review their code
for this pattern and update buffer sizes as presented in the version of
the example in release 12.9.0.

Out-of-bounds Write resulting in possible Heap-based Buffer Overflow vulnerability was discovered in tools/bdf-converter font conversion utility that is part of Apache NuttX RTOS repository. This standalone program is optional and neither part of NuttX RTOS nor Applications runtime, but active bdf-converter users may be affected when this tool is exposed to external provided user data data (i.e. publicly available automation).
This issue affects Apache NuttX: from 6.9 before 12.9.0.
Users are recommended to upgrade to version 12.9.0, which fixes the issue.

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.

An issue was discovered in NuttX before 7.27. The function netlib_parsehttpurl() in apps/netutils/netlib/netlib_parsehttpurl.c mishandles URLs longer than hostlen bytes (in the webclient, this is set by default to 40), leading to an Infinite Loop. The attack vector is the Location header of an HTTP 3xx response.
