Subject: [PATCH] Fix heap overflow in ip_reass on big packet input
|
||||
|
||||
When the first fragment does not fit in the preallocated buffer, q will
|
||||
already be pointing to the ext buffer, so we mustn't try to update it.

While emulating services in tcp_emu(), it uses 'mbuf' size

'm->m_size' to write commands via snprintf(3). Use M_FREEROOM(m)

size to avoid possible OOB access.

Subject: [PATCH] slirp: use correct size while emulating IRC commands
|
||||
|
||||
While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
|
||||
'm->m_size' to write DCC commands via snprintf(3). This may
|
||||
lead to OOB write access, because 'bptr' points somewhere in
|
||||
the middle of 'mbuf' buffer, not at the start. Use M_FREEROOM(m)
|
||||
size to avoid OOB access.
