Astra Linux - уязвимость в mbedtls

A vulnerability was discovered in Mbed TLS before versions 2.28.1 and 3.x, prior to 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server, causing a heap-based buffer overflow of up to 255 bytes. This can lead to a server crash or,...

Astra Linux - уязвимость в 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 - уязвимость в dnsmasq

A issue was discovered in Dnsmasq before version 2.90. The default maximum EDNS.0 UDP packet size was set to 4096, but it should be 1232 due to DNS Flag Day 2020...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: udp: When a connected socket is disconnected, the 4-tuple hash table’s auto-bound connected state is not properly hashed. Suppose we bind a UDP socket to a wildcard address with a non-zero port, connect the socket to a specific...

corosync: Corosync: Denial of Service via integer overflow in join message validation

A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol UDP packets. This can cause the service to crash, leading to a denial of service. This vulnerability...

corosync: Corosync: Denial of Service and information disclosure via crafted UDP packet

A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol UDP packet. This can lead to an out-of-bounds read, causing a denial of service...

ALPINE-CVE-2026-42009

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This...
