SUSE CVE-2015-7219

The HTTP/2 implementation in Mozilla Firefox before 43.0 allows remote attackers to cause a denial of service integer underflow, assertion failure, and application exit via a malformed PushPromise frame that triggers decompressed-buffer length miscalculation and incorrect memory allocation...

SUSE CVE-2015-7218

The HTTP/2 implementation in Mozilla Firefox before 43.0 allows remote attackers to cause a denial of service integer underflow, assertion failure, and application exit via a single-byte header frame that triggers incorrect memory allocation...

SUSE CVE-2016-1546

The Apache HTTP Server 2.4.17 and 2.4.18, when modhttp2 is enabled, does not limit the number of simultaneous stream workers for a single HTTP/2 connection, which allows remote attackers to cause a denial of service stream-processing outage via modified flow-control windows...

SUSE CVE-2016-4979

The Apache HTTP Server 2.4.18 through 2.4.20, when modhttp2 and modssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple...

SUSE CVE-2017-5446

An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird 52.1, Firefox ESR 45.9, Firefox ESR 52.1, and Firefox 53...

SUSE CVE-2017-5650

In Apache Tomcat 9.0.0.M1 to 9.0.0.M18 and 8.5.0 to 8.5.12, the handling of an HTTP/2 GOAWAY frame for a connection did not close streams associated with that connection that were currently waiting for a WINDOWUPDATE before allowing the application to write more data. These waiting streams each...

SUSE CVE-2017-7675

The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M21 and 8.5.0 to 8.5.15 bypassed a number of security checks that prevented directory traversal attacks. It was therefore possible to bypass security constraints using a specially crafted URL...

SUSE CVE-2017-15896

Node.js was affected by OpenSSL vulnerability CVE-2017-3737 in regards to the use of SSLread due to TLS handshake failure. The result was that an active network attacker could send application data to Node.js using the TLS or HTTP2 modules in a way that bypassed TLS authentication and encryption...

SUSE CVE-2018-10184

An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the maxframesize setting instead of being checked against the bufsize. The maxframesize only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the...

SUSE CVE-2018-16843

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngxhttpv2module not compiled by default if the 'http2' option of the 'listen' directive is used in a configuratio...

SUSE CVE-2018-16844

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage. This issue affects nginx compiled with the ngxhttpv2module not compiled by default if the 'http2' option of the 'listen' directive is used in a configuration file...

SUSE CVE-2019-9512

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU,...

SUSE CVE-2019-9513

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU...

SUSE CVE-2019-10072

The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write in Apache Tomcat versions 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOWUPDATE messages for the connection window stream 0 clients were able to cause server-side threads to...

SUSE CVE-2019-11713

A use-after-free vulnerability can occur in HTTP/2 when a cached HTTP/2 stream is closed while still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR 60.8, Firefox 68, and Thunderbird 60.8...

SUSE CVE-2020-11080

In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes 2400 individual settings entries over and over again. The attack causes th...

SUSE CVE-2020-11100

In hpackdhtinsert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution...

SUSE CVE-2020-11996

A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become...

SUSE CVE-2020-11993

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of modhttp2 above "info" will mitigate this...

SUSE CVE-2020-17527

While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this...
