Astra Linux – Vulnerability in Redis

Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious actor with access to the Valkey clusterbus port could send an invalid packet, causing an out-of-bound read operation, which might lead to the system crashing. The Valkey clusterbus packet...

Astra Linux – Vulnerability in Qemu

QEMU 5.0.0 has a use-after-free issue in the hw/usb/hcd-xhci.c file, as the return value of usbpacketmap is not checked...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when calculating packet sizes. Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could lead to an underflow, causing the value to wrap around t...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed an issue where incomplete state saving occurred in rxerequester. If a send packet is dropped by the IP layer in rxerequester, the call to rxexmitpacket may fail with an error code of -EAGAIN. To recover from this...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that the A-MSDU flag in the plaintext QoS header field be authenticated. Against devices that support receiving non-SSP A-MSDU frames which is mandatory as part of...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The can: hi311x module has corrected the ndochangemtu function to prevent buffer overflows. Sending a PFPACKET allows bypassing the CAN driver’s logic and directly reaching the xmit function of the CAN driver. The only check...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-mixer: us16x08: validate meter packet indices The getmeterlevelsfromurb function parses the 64-byte meter packets sent by the device and fills the per-channel arrays meterlevel, complevel, and masterlevel in the struct...

Astra Linux – Vulnerability in libslirp

In ncsi.c within libslirp up to 4.3.1, there is an issue of buffer over-reading. This occurs because the program attempts to read a certain amount of header data, even when that amount exceeds the total packet length...

Astra Linux – Vulnerability in gpsd

There is an integer underflow vulnerability in the nextstate function in gpsd/packet.c in gpsd versions prior to the commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4, without checking whether the input...

Astra Linux – Vulnerability in u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation when parsing a UDP packet, due to an underflow of the netprocessreceivedpacket integer during the udppackethandler call...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: The length of the packet header is validated before calling skbPut. When receiving a vsock packet in the guest, only the size of the virtqueue buffer is validated prior to calling virtiovsockskbrxPut. Unfortunately,...

Astra Linux – Vulnerability in Ruby 2.5

The attack vector is a potential Denial of Service DoS attack. The vulnerability arises from an insufficient check on the length of a decompressed domain name within a DNS packet. An attacker can create a malicious DNS packet containing a highly compressed domain name. When the resolv library...

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: A bug in accessing the uninit variable was fixed in qrtrtxresume. Syzbot reported the bug as follows: ===================================================== Bug: KMSAN: Access to the uninitvalue variable in...

Astra Linux – Vulnerability in Wireshark

A memory leak in the Kafka protocol dissector in Wireshark versions 3.4.0 and 3.2.0 to 3.2.8 allows for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This issue was addressed in the epan/dissectors/packet-nfs.c file by preventing excessive recursion, such as when a cycle occurred in the directory graph of a filesystem...
