DEBIAN-CVE-2026-10051

In Eclipse Jetty, a first HTTP/1.1 request with trailers causes the server to retain the trailers in subsequent requests performed over the same connection. Subsequent request that do not have trailers report the trailers of the first request. Subsequent request that do have trailers report the...

libcurl 8.18.0 < 8.21.0 QUIC UDP Denial of Service (CVE-2026-11352)

The version of libcurl installed on the remote host is 8.18.0 prior to 8.21.0. It is, therefore, affected by a denial of service vulnerability: - An issue in curl's QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client...

netty: io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to improper handling of conflicting HTTP/1.0 headers

A flaw was found in Netty's HttpObjectDecoder. A remote attacker can exploit this by sending a specially crafted HTTP/1.0 request that includes both Transfer-Encoding: chunked and Content-Length headers. While Netty correctly strips the conflicting Content-Length header for HTTP/1.1 messages, thi...

OESA-2026-2980 nghttp2 security update

The framing layer of HTTP/2 is implemented as a form of reusable C library. On top of that, we have implemented HTTP/2 client, server and proxy. We have also developed load test and benchmarking tool for HTTP/2. Security Fixes: nghttp2's nghttpx proxy through 1.69.0 forwards an HTTP/1.1 Upgrade...

ROS-20260709-73-0023

The vulnerability in the HTTP/2 implementation using the Go programming language arises from executing a loop with an unreachable exit condition when processing the value of SETTINGSMAXFRAMESIZE, which is equal to 0. Exploiting this vulnerability could allow a remote attacker to cause a service...

CVE-2026-10536

A flaw was found in libcurl. This use-after-free vulnerability occurs when an application configures an HTTP/2 stream-dependency tree and then performs a sequence of operations involving curleasyreset and curleasycleanup. During the final cleanup, libcurl attempts to access memory that has alread...

SUSE-SU-2026:22553-1 Security update for curl

This update for curl fixes the following issues - CVE-2026-8286: wrong STARTTLS connection reuse bsc1268402. - CVE-2026-8458: wrong reuse for different services bsc1268407. - CVE-2026-8924: traling dot domain super cookie bsc1268409. - CVE-2026-8927: env-set cross-proxy Digest auth state leak...

httpd: httpd: HTTP/2 Remote Denial of Service via compression bomb and Slowloris-style attack

A flaw was found in HTTP/2, affecting various web servers. A remote attacker can exploit this vulnerability by combining an HPACK compression bomb with a zero-byte flow-control window. This technique allows a small amount of data to expand into large memory allocations on the server, which are th...

SUSE-SU-2026:22567-1 Security update for docker-compose

This update for docker-compose fixes the following issues - CVE-2025-0495: buildx: credential leakage to telemetry endpoints when credentials allowed to be set as attribute values in cache-to/cache-from configuration bsc1239766. - CVE-2025-22869: golang.org/x/crypto/ssh: Denial of Service in the...

PYSEC-2026-1427 Connection confusion in gRPC

When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this...

CVE-2026-10536 HTTP/2 stream-dependency tree UAF

A use-after-free vulnerability exists in libcurl when an application configures an HTTP/2 stream-dependency tree via CURLOPTSTREAMDEPENDS or CURLOPTSTREAMDEPENDSE, subsequently invokes curleasyreset, and finally terminates the handle with curleasycleanup. During this final cleanup phase, libcurl...

curl: libcurl: curl/libcurl: Remote denial of service via QUIC UDP receive function vulnerability

A flaw was found in curl and libcurl. A malicious HTTP/3 server can exploit an issue in the QUIC UDP receive function by continuously streaming empty UDP datagrams. This can lead to a remote denial of service DoS against a curl or libcurl client, as the helper function discards zero-length UDP...
