-Subject: [PATCH] iscsi: Cap block count from GET LBA STATUS (CVE-2020-1711)
-
-When querying an iSCSI server for the provisioning status of blocks (via
-GET LBA STATUS), Qemu only validates that the response descriptor zero's
-LBA matches the one requested. Given the SCSI spec allows servers to
-respond with the status of blocks beyond the end of the LUN, Qemu may
-have its heap corrupted by clearing/setting too many bits at the end of
-its allocmap for the LUN.
-
-A malicious guest in control of the iSCSI server could carefully program
-Qemu's heap (by selectively setting the bitmap) and then smash it.
-
-This limits the number of bits that iscsi_co_block_status() will try to
-update in the allocmap so it can't overflow the bitmap.
-

-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.

-Subject: [PATCH] tcp_emu: fix unsafe snprintf() usages
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Various calls to snprintf() assume that snprintf() returns "only" the
-number of bytes written (excluding terminating NUL).
-
-https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html#tag_16_159_04
-
-"Upon successful completion, the snprintf() function shall return the
-number of bytes that would be written to s had n been sufficiently
-large excluding the terminating null byte."
-
-Before patch ce131029, if there isn't enough room in "m_data" for the
-"DCC ..." message, we overflow "m_data".
-
-After the patch, if there isn't enough room for the same, we don't
-overflow "m_data", but we set "m_len" out-of-bounds. The next time an
-access is bounded by "m_len", we'll have a buffer overflow then.
-
-Use slirp_fmt*() to fix potential OOB memory access.

-Subject: [PATCH] util: add slirp_fmt() helpers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Various calls to snprintf() in libslirp assume that snprintf() returns
-"only" the number of bytes written (excluding terminating NUL).
-
-https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html#tag_16_159_04
-
-"Upon successful completion, the snprintf() function shall return the
-number of bytes that would be written to s had n been sufficiently
-large excluding the terminating null byte."
-
-Introduce slirp_fmt() that handles several pathological cases the
-way libslirp usually expect:
-
-- treat error as fatal (instead of silently returning -1)
-
-- fmt0() will always \0 end
-
-- return the number of bytes actually written (instead of what would
-have been written, which would usually result in OOB later), including
-the ending \0 for fmt0()
-
-- warn if truncation happened (instead of ignoring)
-
-Other less common cases can still be handled with strcpy/snprintf() etc.
