Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: ipvti: A potential issue related to slab-use-after-free has been fixed in decodesession6. When the ipvti device is set as a qdisc of the sfb type, the cb field of the sent skb may be modified during enqueueing. This can lead to a...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: mptcp: handle large GSO sizes After the committed code below, TCP sockets and MPTCP subflows can generate egress packets that are larger than 64K. This exceeds the maximum DSS data size; the packet length is misrepresented over t...
Astra Linux – Vulnerability in OVN
A flaw was discovered in the Open Virtual Network OVN. Specially crafted UDP packets may bypass egress access control lists ACLs in OVN installations that are configured with a logical switch equipped with DNS records. This occurs if the same switch has any egress ACLs configured. This issue can...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: Bonding: Fix for xfrm realdev null pointer dereference We should not set realdev to NULL, because packets may still be in transit, and xfrm might call xdodevoffloadok in parallel. All callbacks assume that realdev is set. Example...
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...
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 bluez
BlueZ is a Bluetooth protocol stack for Linux. In affected versions, there is a vulnerability in sdpcstateallocbuf, which allocates memory that will always remain locked in the singly linked list of cstates and will not be freed. This will lead to a memory leak over time. The allocated data can b...
Astra Linux – Vulnerability in Wireshark
ISO 15765 and ISO 10681 dissectors in Wireshark versions 4.0.0 to 4.0.3, and 3.6.0 to 3.6.11 allow denial of service through packet injection or malicious capture files...
Astra Linux – Vulnerability in Wireshark
The XRA dissector infinite loop in Wireshark versions 4.0.0 to 4.0.5, and 3.6.0 to 3.6.13 allows for denial of service through packet injection or malicious capture files...
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 – 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 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...
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 – 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 libslirp
An invalid pointer initialization issue was discovered in the SLiRP networking implementation of QEMU. The flaw exists in the udpinput function and can occur when processing an UDP packet that is smaller than the size of the ‘udphdr’ structure. This issue may lead to out-of-bounds read access or...
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 OpenVSwitch
A flaw was discovered in OpenVSwitch OVS. When processing an IP packet with protocol 0, OVS will install a datapath flow without modifying the IP header. This issue results in the installation of a datapath flow that matches all IP protocols with “nwproto” set to wildcard, but with an incorrect...
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...
