Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: ppp: Rejects packets that are claimed to be LCP packets but are actually malformed packets. Since pppasyncencode assumes that the packets are valid LCP packets with codes from 1 to 7 inclusive, add pppcheckpacket to ensure that t...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: IB/core: A limit has been implemented on the size of the UMAD receive list. The current behavior of ibumad—which maintains received MAD packets in an unbounded list—poses a risk of uncontrolled growth. As user-space applications...

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: net: ppp: Added bound checking for skb data in pppsynctxmung. We ensure that we have enough data in the linear buffer from the skb before accessing the initial bytes. This prevents potential out-of-bounds accesses when processing...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: mvm – Ensure that the queue for the offloaded TID exists. The resume code path assumes that the TX queue for the offloaded TID has been configured. At the time of resuming operations, it attempts to synchronize the...

Astra Linux – Vulnerability in Corosync

A flaw was discovered in Corosync. There is an integer overflow vulnerability in Corosync’s join message sanity validation mechanism, which allows a remote, unauthenticated attacker to send crafted User Datagram Protocol UDP packets. This can cause the service to crash, resulting in a denial of...

Astra Linux – Vulnerability in Wireshark

Excessive memory consumption in the MS-WSP dissector in Wireshark versions 3.4.0 to 3.4.4, and 3.2.0 to 3.2.12 may allow denial of service through packet injection or crafted capture files...

Astra Linux – Vulnerability in OVN

A flaw was discovered in the Open Virtual Network OVN. In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from within unprivileged workloads, including virtual machines or containers, which can trigger a denial of...

Astra Linux – Vulnerability in Wireshark

A crash in the CMS protocol dissector in Wireshark versions 3.6.0 to 3.6.1 and 3.4.0 to 3.4.11 allows for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux SCTP stack. A blind attacker may be able to terminate an existing SCTP connection by using invalid chunks, provided that the attacker knows the IP addresses and port numbers being used, and that the attacker can send packets with spoofed IP addresses...

Astra Linux – Vulnerability in wpa

There exists a exploitable denial-of-service vulnerability in hostapd 2.6. An attacker could trigger the AP to send IAPP location updates for stations, even before the required authentication process is completed. This could lead to various denial-of-service scenarios, either by causing CAM table...

USN-8754-1 freeciv vulnerability

It was discovered that Freeciv incorrectly handled certain network packets, resulting in a stack overflow. A remote attacker could possibly use this issue to cause Freeciv clients or servers to crash, resulting in a denial of service...

USN-8754-1: Freeciv vulnerability

It was discovered that Freeciv incorrectly handled certain network packets, resulting in a stack overflow. A remote attacker could possibly use this issue to cause Freeciv clients or servers to crash, resulting in a denial of service...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: fixed a slab-use-after-free issue in decodeSession6 When the xfrm device is set to the qdisc of the sfb type, the cb field of the sentskb may be modified during enqueuing. This can lead to a slab-use-after-free when the xfr...

Astra Linux – Vulnerability in Wireshark

The SSH dissector in Wireshark versions 4.0.0 to 4.0.10 allows for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerability in OpenVSwitch

A flaw was discovered in Open vSwitch, where multiple versions are vulnerable to crafted Geneve packets, which may lead to a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled...

Astra Linux – Vulnerability in NTP

In ntp 4.2.8p10, 4.2.8p11, 4.2.8p12, and 4.2.8p13, remote attackers can prevent a broadcast client from synchronizing its clock with a broadcast NTP server through soofed modes 3 and 5. The attacker must either be part of the same broadcast network or control a slave device in that broadcast...

Astra Linux – Vulnerability in Linux

A vulnerability was discovered in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory...

Astra Linux – Vulnerability in Wireshark

An infinite loop in the BitTorrent DHT dissector in Wireshark versions 3.6.0, 3.4.0, and 3.4.10 allows for denial of service through packet injection or malicious capture files...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

A flaw was discovered in the Linux kernel’s NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packets when using NVMe over TCP. This can lead to the NVMe driver dereferencing a NULL pointer, resulting in kernel panic and a denial of service...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba’s WINS server component when running as an Active Directory Domain Controller. The WINS protocol handlers for certain request types did not properly validate incoming packets, allowing an unauthenticated remote attacker to trigger a NULL pointer dereference and caus...
