GHSA-856Q-XV3C-7F2F Unauthenticated control plane denial of service attack in Istio

Impact The Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted message which results in the control plane crashing. This endpoint is served over TLS port 15012, but does not require any authentication from the...

CVE-2022-24704

The radpacketrecv function in opt/src/accel-pppd/radius/packet.c suffers from a buffer overflow vulnerability, whereby user input len is copied into a fixed buffer &attr-val.integer without any bound checks. If the client connects to the server and sends a large radius packet, a buffer overflow...

Buffer overflow

The radpacketrecv function in opt/src/accel-pppd/radius/packet.c suffers from a buffer overflow vulnerability, whereby user input len is copied into a fixed buffer &attr-val.integer without any bound checks. If the client connects to the server and sends a large radius packet, a buffer overflow...

Buffer overflow

The radpacketrecv function in radius/packet.c suffers from a memcpy buffer overflow, resulting in an overly-large recvfrom into a fixed buffer that causes a buffer overflow and overwrites arbitrary memory. If the server connects with a malicious client, crafted client requests can remotely trigge...

CVE-2022-24705 Buffer Overflow via Crafted Ipv6 Prefix Attribute Type Client Request in accel-ppp v1.12

The radpacketrecv function in radius/packet.c suffers from a memcpy buffer overflow, resulting in an overly-large recvfrom into a fixed buffer that causes a buffer overflow and overwrites arbitrary memory. If the server connects with a malicious client, crafted client requests can remotely trigge...

CVE-2022-24705

The CVE-2022-24705 vulnerability is in accel-ppp (Accel-PPP) where the rad_packet_recv function in radius/packet.c uses a memcpy into a fixed-size buffer, enabling a buffer overflow when receiving crafted client requests. This can be triggered remotely by a malicious client over the network, pote...

CVE-2022-24704

CVE-2022-24704 affects the accel-ppp project, specifically the function rad_packet_recv in opt/src/accel-pppd/radius/packet.c . The vulnerability arises because user input length is copied into a fixed buffer and into attr->val.integer without bounds checks, leading to a buffer overflow when a...
