SUSE CVE-2026-34183

Issue summary: Remote peer may exhaust heap memory of the QUIC server or client by flooding it with packets containing PATHCHALLENGE frames. Impact summary: A malicious remote peer can cause an unbounded memory allocation which can lead to an abnormal termination of the application acting as a QU...

openssl: Unbounded Memory Growth in the QUIC PATH_CHALLENGE Handler

A flaw was found in OpenSSL's QUIC PATHCHALLENGE handler. A remote attacker can exploit this vulnerability by flooding a QUIC client or server with specially crafted PATHCHALLENGE frames. This leads to unbounded memory allocation within the local QUIC stack, as the system continuously allocates...

CBL Mariner 2.0 Security Update: coredns (CVE-2023-49295)

The version of coredns installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-49295 advisory. - quic-go is an implementation of the QUIC protocol RFC 9000, RFC 9001, RFC 9002 in Go. An attacker can cause...

SUSE CVE-2023-49295

quic-go is an implementation of the QUIC protocol RFC 9000, RFC 9001, RFC 9002 in Go. An attacker can cause its peer to run out of memory sending a large number of PATHCHALLENGE frames. The receiver is supposed to respond to each PATHCHALLENGE frame with a PATHRESPONSE frame. The attacker can...

quic-go: memory exhaustion attack against QUIC's path validation mechanism

A memory exhaustion vulnerability was found in Quic-GO, where a malicious client exploits the path validation mechanism to induce the server into accumulating an unbounded queue of PATHRESPONSE frames, depleting its memory. The attacker controls the victim's packet send rate by overwhelming the...

Name of the Vulnerable Software and Affected Versions: quiche versions 0.15.0 through 0.19.0 Description: The issue is related to unbounded queuing of path validation messages, which could lead to excessive resource consumption. QUIC path validation requires that the recipient of a PATH CHALLENGE...

FTP PWD response parser out of bounds read

libcurl may read outside of a heap allocated buffer when doing FTP. When libcurl connects to an FTP server and successfully logs in anonymous or not, it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double...
