| marshall in dhcp_packet.c in simple-dhcp-server through ec976d2 allows remote attackers to cause a denial of service by sending a malicious DHCP packet. The crash is caused by a type confusion bug that results in a large memory allocation; when this memory allocation fails the DHCP server will crash. |
| emdns_resolve_raw in emdns.c in emdns through fbd1eef calls strlen with an input that may not be '\0' terminated, leading to a stack-based buffer over-read. This can be triggered by a remote adversary that can send DNS requests to the emdns server. The impact could vary depending on the system libraries, compiler, and processor architecture. Code before be565c3 is unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
m68k: mm: Move initrd phys_to_virt handling after paging_init()
When booting with an initial ramdisk on platforms where physical memory
does not start at address zero (e.g. on Amiga):
initrd: 0ef0602c - 0f800000
Zone ranges:
DMA [mem 0x0000000008000000-0x000000f7ffffffff]
Normal empty
Movable zone start for each node
Early memory node ranges
node 0: [mem 0x0000000008000000-0x000000000f7fffff]
Initmem setup node 0 [mem 0x0000000008000000-0x000000000f7fffff]
Unable to handle kernel access at virtual address (ptrval)
Oops: 00000000
Modules linked in:
PC: [<00201d3c>] memcmp+0x28/0x56
As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must
not be called before paging_init(). Hence postpone the phys_to_virt
handling for the initial ramdisk until after calling paging_init().
While at it, reduce #ifdef clutter by using IS_ENABLED() instead. |
| vulnerability in Uniform Server Zero, version 10.2.5, consisting of an XSS through the /us_extra/phpinfo.php page. This vulnerability could allow a remote user to send a specially crafted query to an authenticated user and partially take over their session details. |
| A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an attacker to potentially gain remote code execution or cause denial of service via the channel definition cdef atom of JPEG2000. |

dm thin: Fix UAF in run_timer_softirq()
When dm_resume() and dm_destroy() are concurrent, it will
lead to UAF, as follows:

One of the concurrency UAF can be shown as below:
use free
do_resume |
__find_device_hash_cell |
dm_get |
atomic_inc(&md->holders) |
| dm_destroy
| __dm_destroy
| if (!dm_suspended_md(md))
| atomic_read(&md->holders)
| msleep(1)
dm_resume |
__dm_resume |
dm_table_resume_targets |
pool_resume |
do_waker #add delay work |
dm_put |
atomic_dec(&md->holders) |
| dm_table_destroy
| pool_dtr
| __pool_dec
| __pool_destroy
| destroy_workqueue
| kfree(pool) # free pool
time out
__do_softirq
run_timer_softirq # pool has already been freed
This can be easily reproduced using:
1. create thin-pool
2. dmsetup suspend pool
3. dmsetup resume pool
4. dmsetup remove_all # Concurrent with 3
The root cause of this UAF bug is that dm_resume() adds timer after
dm_destroy() skips cancelling the timer because of suspend status.
After timeout, it will call run_timer_softirq(), however pool has
already been freed. The concurrency UAF bug will happen.
Therefore, cancelling timer again in __pool_destroy(). |

s390/netiucv: Fix return type of netiucv_tx()
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:
drivers/s390/net/netiucv.c:1854:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = netiucv_tx,
^~~~~~~~~~
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of netiucv_tx() to
match the prototype's to resolve the warning and potential CFI failure,
should s390 select ARCH_SUPPORTS_CFI_CLANG in the future.
Additionally, while in the area, remove a comment block that is no
longer relevant. |

fs: jfs: fix shift-out-of-bounds in dbAllocAG
Syzbot found a crash : UBSAN: shift-out-of-bounds in dbAllocAG. The
underlying bug is the missing check of bmp->db_agl2size. The field can
be greater than 64 and trigger the shift-out-of-bounds.
Fix this bug by adding a check of bmp->db_agl2size in dbMount since this
field is used in many following functions. The upper bound for this
field is L2MAXL2SIZE - L2MAXAG, thanks for the help of Dave Kleikamp.
Note that, for maintenance, I reorganized error handling code of dbMount. |
