fetch_newgroups_tok(3): clamp group count to AUDIT_MAX_GROUPS before the loop to prevent a stack buffer overflow when a crafted record specifies more than 16 groups. fetch_execarg_tok(3), fetch_execenv_tok(3): add a bounds check at the top of the string-walking loop to prevent an out-of-bounds read when the previous string's nul byte is the last byte of the record buffer. fetch_sock_unix_tok(3): clamp the memchr search length to the number of bytes remaining in the buffer to prevent an out-of-bounds read on short tokens. Also clamp slen to sizeof(path) to prevent a one-byte overflow when no nul byte is found within the path data. fetch_socket_tok: fix copy-paste error where the remote address was written into l_addr instead of r_addr. Previously reported by: @haginara Define AU_UNIX_PATH_MAX as 108 (the largest sun_path across all supported platforms) and use it in au_socketunix_t instead of the hardcoded 104. Update fetch_sock_unix_tok to derive its search bound from sizeof(tok->tt.sockunix.path) so cross-platform records from Solaris and Linux with paths up to 108 bytes parse correctly without truncation.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
