| In the Linux kernel, the following vulnerability has been resolved:
tcp: add sanity tests to TCP_QUEUE_SEQ
Qingyu Li reported a syzkaller bug where the repro
changes RCV SEQ _after_ restoring data in the receive queue.
mprotect(0x4aa000, 12288, PROT_READ) = 0
mmap(0x1ffff000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x1ffff000
mmap(0x20000000, 16777216, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x20000000
mmap(0x21000000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x21000000
socket(AF_INET6, SOCK_STREAM, IPPROTO_IP) = 3
setsockopt(3, SOL_TCP, TCP_REPAIR, [1], 4) = 0
connect(3, {sa_family=AF_INET6, sin6_port=htons(0), sin6_flowinfo=htonl(0), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_scope_id=0}, 28) = 0
setsockopt(3, SOL_TCP, TCP_REPAIR_QUEUE, [1], 4) = 0
sendmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="0x0000000000000003\0\0", iov_len=20}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 20
setsockopt(3, SOL_TCP, TCP_REPAIR, [0], 4) = 0
setsockopt(3, SOL_TCP, TCP_QUEUE_SEQ, [128], 4) = 0
recvfrom(3, NULL, 20, 0, NULL, NULL) = -1 ECONNRESET (Connection reset by peer)
syslog shows:
[ 111.205099] TCP recvmsg seq # bug 2: copied 80, seq 0, rcvnxt 80, fl 0
[ 111.207894] WARNING: CPU: 1 PID: 356 at net/ipv4/tcp.c:2343 tcp_recvmsg_locked+0x90e/0x29a0
This should not be allowed. TCP_QUEUE_SEQ should only be used
when queues are empty.
This patch fixes this case, and the tx path as well. |
| In the Linux kernel, the following vulnerability has been resolved:
media: dvbdev: Fix memory leak in dvb_media_device_free()
dvb_media_device_free() is leaking memory. Free `dvbdev->adapter->conn`
before setting it to NULL, as documented in include/media/media-device.h:
"The media_entity instance itself must be freed explicitly by the driver
if required." |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: Fix a potential use after free
Free the adap structure only after we are done using it.
This patch just moves the put_device() down a bit to avoid the
use after free.
[wsa: added comment to the code, added Fixes tag] |
| In the Linux kernel, the following vulnerability has been resolved:
netlabel: fix out-of-bounds memory accesses
There are two array out-of-bounds memory accesses, one in
cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both
errors are embarassingly simple, and the fixes are straightforward.
As a FYI for anyone backporting this patch to kernels prior to v4.8,
you'll want to apply the netlbl_bitmap_walk() patch to
cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before
Linux v4.8. |

| A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host. |
| The redirect_to method in Rails allows provided values to contain characters which are not legal in an HTTP header value. This results in the potential for downstream services which enforce RFC compliance on HTTP response headers to remove the assigned Location header. |
| In libpixman in Pixman before 0.42.2, there is an out-of-bounds write (aka heap-based buffer overflow) in rasterize_edges_8 due to an integer overflow in pixman_sample_floor_y. |
| A buffer overflow was discovered in NTFS-3G before 2022.10.3. Crafted metadata in an NTFS image can cause code execution. A local attacker can exploit this if the ntfs-3g binary is setuid root. A physically proximate attacker can exploit this if NTFS-3G software is configured to execute upon attachment of an external storage device. |
| With Apache Ivy 2.4.0 an optional packaging attribute has been introduced that allows artifacts to be unpacked on the fly if they used pack200 or zip packaging. For artifacts using the "zip", "jar" or "war" packaging Ivy prior to 2.5.1 doesn't verify the target path when extracting the archive. An archive containing absolute paths or paths that try to traverse "upwards" using ".." sequences can then write files to any location on the local fie system that the user executing Ivy has write access to. Ivy users of version 2.4.0 to 2.5.0 should upgrade to Ivy 2.5.1. |
| Fedora CoreOS supports setting a GRUB bootloader password
using a Butane config. When this feature is enabled, GRUB requires a password to access the
GRUB command-line, modify kernel command-line arguments, or boot
non-default OSTree deployments. Recent Fedora CoreOS releases have a
misconfiguration which allows booting non-default OSTree deployments
without entering a password. This allows someone with access to the
GRUB menu to boot into an older version of Fedora CoreOS, reverting
any security fixes that have recently been applied to the machine. A
password is still required to modify kernel command-line arguments and
to access the GRUB command line.

| An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service. |
| base-x is a base encoder and decoder of any given alphabet using bitcoin style leading zero compression. Versions 4.0.0, 5.0.0, and all prior to 3.0.11, are vulnerable to attackers potentially deceiving users into sending funds to an unintended address. This issue has been patched in versions 3.0.11, 4.0.1, and 5.0.1. |
| When Apache Ivy downloads artifacts from a repository it stores them in the local file system based on a user-supplied "pattern" that may include placeholders for artifacts coordinates like the organisation, module or version. If said coordinates contain "../" sequences - which are valid characters for Ivy coordinates in general - it is possible the artifacts are stored outside of Ivy's local cache or repository or can overwrite different artifacts inside of the local cache. In order to exploit this vulnerability an attacker needs collaboration by the remote repository as Ivy will issue http requests containing ".." sequences and a "normal" repository will not interpret them as part of the artifact coordinates. Users of Apache Ivy 2.0.0 to 2.5.1 should upgrade to Ivy 2.5.1. |
| SSH servers which implement file transfer protocols are vulnerable to a denial of service attack from clients which complete the key exchange slowly, or not at all, causing pending content to be read into memory, but never transmitted. |
| An attacker can pass a malicious malformed token which causes unexpected memory to be consumed during parsing. |
