| When a SecurityManager is configured, a web application's ability to read system properties should be controlled by the SecurityManager. In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70, 6.0.0 to 6.0.45 the system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible. |
| ActionServlet.java in Apache Struts 1 1.x through 1.3.10 mishandles multithreaded access to an ActionForm instance, which allows remote attackers to execute arbitrary code or cause a denial of service (unexpected memory access) via a multipart request, a related issue to CVE-2015-0899. |
| Unspecified vulnerability in the Java SE and Java SE Embedded components in Oracle Java SE 6u105, 7u91, and 8u66 and Java SE Embedded 8u65 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D. |
| Unspecified vulnerability in Oracle Java SE 6u105, 7u91, and 8u66; Java SE Embedded 8u65; and JRockit R28.3.8 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to AWT. NOTE: the previous information is from the January 2016 CPU. Oracle has not commented on third-party claims that this is a heap-based buffer overflow in the readImage function, which allows remote attackers to execute arbitrary code via crafted image data. |

| In the Linux kernel, the following vulnerability has been resolved:
ublk: reset per-IO canceled flag on each fetch
If a ublk server starts recovering devices but dies before issuing fetch
commands for all IOs, cancellation of the fetch commands that were
successfully issued may never complete. This is because the per-IO
canceled flag can remain set even after the fetch for that IO has been
submitted - the per-IO canceled flags for all IOs in a queue are reset
together only once all IOs for that queue have been fetched. So if a
nonempty proper subset of the IOs for a queue are fetched when the ublk
server dies, the IOs in that subset will never successfully be canceled,
as their canceled flags remain set, and this prevents ublk_cancel_cmd
from actually calling io_uring_cmd_done on the commands, despite the
fact that they are outstanding.
Fix this by resetting the per-IO cancel flags immediately when each IO
is fetched instead of waiting for all IOs for the queue (which may never
happen). |
| In the Linux kernel, the following vulnerability has been resolved:
tun: free page on short-frame rejection in tun_xdp_one()
tun_xdp_one() returns -EINVAL on a frame shorter than ETH_HLEN without
freeing the page that vhost_net_build_xdp() allocated for it.
tun_sendmsg() discards that -EINVAL and still returns total_len, so
vhost_tx_batch() takes the success path and never frees the page; each
short frame in a batch leaks one page-frag chunk.
A local process that can open /dev/net/tun and /dev/vhost-net can hit
this path: it attaches a tun/tap device as the vhost-net backend and
feeds TX descriptors whose length minus the virtio-net header is below
ETH_HLEN. Each kick leaks the page-frag chunks for that batch, and a
tight submission loop exhausts host memory and triggers an OOM panic.
Free the page before returning -EINVAL, matching the XDP-program error
path in the same function. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: reject userspace cifs.spnego descriptions
cifs.spnego key descriptions contain authority-bearing fields such as
pid, uid, creduid, and upcall_target that cifs.upcall treats as
kernel-originating inputs. However, userspace can also create keys of
this type through request_key(2) or add_key(2), allowing those fields to
be supplied without CIFS origin.
Only accept cifs.spnego descriptions while CIFS is using its private
spnego_cred to request the key. |
| In the Linux kernel, the following vulnerability has been resolved:
ipmi: Add limits to event and receive message requests
The driver would just fetch events and receive messages until the
BMC said it was done. To avoid issues with BMCs that never say they are
done, add a limit of 10 fetches at a time.
In addition, an si interface has an attn state it can return from the
hardware which is supposed to cause a flag fetch to see if the driver
needs to fetch events or message or a few other things. If the attn
bit gets stuck, it's a similar problem. So allow messages in between
flag fetches so the driver itself doesn't get stuck.
This is a more general fix than the previous fix for the specific bad
BMC, but should fix the more general issue of a BMC that won't stop
saying it has data.
This has been there from the beginning of the driver. It's not a bug
per-se, but it is accounting for bugs in BMCs. |
| In the Linux kernel, the following vulnerability has been resolved:
ipmi: Check event message buffer response for bad data
The event message buffer response data size got checked later when
processing, but check it right after the response comes back. It
appears some BMCs may return an empty message instead of an error
when fetching events.
There are apparently some new BMCs that make this error, so we need to
compensate. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: handle zerocopy send cleanup before the message is queued
A zerocopy send can fail after user pages have been pinned but before
the message is attached to the sending socket.
The purge path currently infers zerocopy state from rm->m_rs, so an
unqueued message can be cleaned up as if it owned normal payload pages.
However, zerocopy ownership is really determined by the presence of
op_mmp_znotifier, regardless of whether the message has reached the
socket queue.
Capture op_mmp_znotifier up front in rds_message_purge() and use it as
the cleanup discriminator. If the message is already associated with a
socket, keep the existing completion path. Otherwise, drop the pinned
page accounting directly and release the notifier before putting the
payload pages.
This keeps early send failure cleanup consistent with the zerocopy
lifetime rules without changing the normal queued completion path. |
| In the Linux kernel, the following vulnerability has been resolved:
net: correctly handle tunneled traffic on IPV6_CSUM GSO fallback
NETIF_F_IPV6_CSUM only advertises support for checksum offload of
packets without IPv6 extension headers. Packets with extension
headers must fall back onto software checksumming. Since TSO
depends on checksum offload, those must revert to GSO.
The below commit introduces that fallback. It always checks
network header length. For tunneled packets, the inner header length
must be checked instead. Extend the check accordingly.
A special case is tunneled packets without inner IP protocol. Such as
RFC 6951 SCTP in UDP. Those are not standard IPv6 followed by
transport header either, so also must revert to the software GSO path. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ti-adc161s626: use DMA-safe memory for spi_read()
Add a DMA-safe buffer and use it for spi_read() instead of a stack
memory. All SPI buffers must be DMA-safe.
Since we only need up to 3 bytes, we just use a u8[] instead of __be16
and __be32 and change the conversion functions appropriately. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ftgmac100: fix ring allocation unwind on open failure
ftgmac100_alloc_rings() allocates rx_skbs, tx_skbs, rxdes, txdes, and
rx_scratch in stages. On intermediate failures it returned -ENOMEM
directly, leaking resources allocated earlier in the function.
Rework the failure path to use staged local unwind labels and free
allocated resources in reverse order before returning -ENOMEM. This
matches common netdev allocation cleanup style. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: use check_add_overflow() to prevent u16 DACL size overflow
set_posix_acl_entries_dacl() and set_ntacl_dacl() accumulate ACE sizes
in u16 variables. When a file has many POSIX ACL entries, the
accumulated size can wrap past 65535, causing the pointer arithmetic
(char *)pndace + *size to land within already-written ACEs. Subsequent
writes then overwrite earlier entries, and pndacl->size gets a
truncated value.
Use check_add_overflow() at each accumulation point to detect the
wrap before it corrupts the buffer, consistent with existing
check_mul_overflow() usage elsewhere in smbacl.c. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_ncm: validate minimum block_len in ncm_unwrap_ntb()
The block_len read from the host-supplied NTB header is checked against
ntb_max but has no lower bound. When block_len is smaller than
opts->ndp_size, the bounds check of:
ndp_index > (block_len - opts->ndp_size)
will underflow producing a huge unsigned value that ndp_index can never
exceed, defeating the check entirely.
The same underflow occurs in the datagram index checks against block_len
- opts->dpe_size. With those checks neutered, a malicious USB host can
choose ndp_index and datagram offsets that point past the actual
transfer, and the skb_put_data() copies adjacent kernel memory into the
network skb.
Fix this by rejecting block lengths that cannot hold at least the NTB
header plus one NDP. This will make block_len - opts->ndp_size and
block_len - opts->dpe_size both well-defined.
Commit 8d2b1a1ec9f5 ("CDC-NCM: avoid overflow in sanity checking") fixed
a related class of issues on the host side of NCM. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate EaNameLength in smb2_get_ea()
smb2_get_ea() reads ea_req->EaNameLength from the client request and
passes it directly to strncmp() as the comparison length without
verifying that the length of the name really is the size of the input
buffer received.
Fix this up by properly checking the size of the name based on the value
received and the overall size of the request, to prevent a later
strncmp() call to use the length as a "trusted" size of the buffer.
Without this check, uninitialized heap values might be slowly leaked to
the client. |
